SCDM CCDM Sample Questions
Question # 1
QUESTION 150
On a dose escalation study, the Data Manager notices one site has a much higher number of queries
than other sites and most are older than 30 days. The Data Safety Monitoring Board will meet in
three weeks. What should the Data Manager providing CRO oversight do?
A. Notify the CRO's Clinical Leader about the concerns B. Call the site directly and ask the study coordinator about the concerns C. Consult the CRO's Lead Data Manager and the CRO's Project Leader D. Ignore it for now and check back next week
Answer: C Explanation:
The correct action is to consult the CROs Lead Data Manager and CROs Project Leader (Option C) to
ensure the issue is addressed through the appropriate oversight and escalation process.
According to the GCDMP (Chapter: Project Management and Communication), when a sponsor Data
Manager identifies significant data management issues under CRO oversight ” such as aging queries
or site performance disparities ” communication must follow the established governance and
escalation pathway defined in the Scope of Work (SOW) and Data Management Plan (DMP).
Directly contacting the site (Option B) bypasses the CROs chain of command and violates
communication protocols. Notifying only the Clinical Leader (Option A) is insufficient, and ignoring
the issue (Option D) jeopardizes the Data Safety Monitoring Board (DSMB) review timeline.
Therefore, Option C ensures a documented, collaborative approach to problem resolution within the
contractual oversight structure.

Question # 2
In reviewing the adverse events for a subject, a data manager notices one recorded as "worsening of
migraine." After reviewing the rest of the adverse events and finding no other migraine recordings,
what is the data manager's next step?
A. Look for any adverse event instance of headache and assume the events are similar. B. Query the site for the first adverse event occurrence of migraine. C. Check the medical history for recording of a history of migraines. D. Query the site for more information on the adverse event, "worsening of migraine."
Answer: D Explanation:
When a data inconsistency arises ” such as a record of œworsening of migraine without prior
documentation of a migraine episode ” the Data Manager should query the site for clarification (Option D).
According to the GCDMP (Chapter: Data Validation and Cleaning), data managers must raise a
clarification query whenever data appear incomplete, inconsistent, or ambiguous. The site must
confirm whether œworsening of migraine refers to a new event or an exacerbation of a preexisting
condition. This clarification ensures accurate safety reporting and appropriate medical coding (e.g., MedDRA classification).
Checking the medical history (Option C) may help but does not resolve the inconsistency. Assuming a
relationship (Option A or B) without verification would violate Good Clinical Data Management
Practice and potentially misrepresent the adverse event.

Question # 3
What significant difference is there in the DM role when utilizing an EDC application?
A. Data updates are implemented by the sites B. Database validation is not required C. Metrics generation is required D. Tracking of eCRFs is a monitor's responsibility
Answer: A Explanation:
The most significant difference in the Data Managers role when using an Electronic Data Capture
(EDC) system is that data updates are implemented directly by site personnel (Option A).
According to the GCDMP (Chapter: Electronic Data Capture Systems), EDC technology shifts
responsibility for data entry and correction from the sponsor or CRO to the investigator site, enabling
real-time data entry and validation. This eliminates the need for double entry or remote data
transcription, allowing Data Managers to focus on system validation, query management, and data
quality oversight rather than physical data handling.
However, the EDC system still requires full validation (contrary to Option B). Metrics generation
(Option C) and CRF tracking (Option D) are important but not unique to EDC-based workflows.
Thus, the correct answer is Option A “ Data updates are implemented by the sites, reflecting the
most fundamental operational shift introduced by EDC systems.

Question # 4
Which protocol section most concisely conveys timing of data collection throughout a study?
A. Study endpoints section B. Study schedule of events C. Protocol synopsis D. ICH essential documents
Answer: B Explanation:
The Study Schedule of Events (SoE) section in the protocol is the most concise and comprehensive
representation of the timing of data collection throughout a study.
According to the Good Clinical Data Management Practices (GCDMP, Chapter: Data Management
Planning and Study Start-up) and ICH E6 (R2) GCP, the SoE outlines what assessments, procedures,
and data collections occur at each study visit (e.g., screening, baseline, treatment visits, follow-up).
This table is a foundational tool for CRF design, database structure, and edit-check development,
ensuring alignment between the protocol and data management systems. While the study endpoints section (A) defines what is measured, and the protocol synopsis (C)
summarizes the design, only the schedule of events (B) specifies when data collection occurs for each
parameter. The ICH essential documents (D) pertain to regulatory documentation, not study visit
timing.

Question # 5
A Data Manager is designing a report to facilitate discussions with sites regarding late dat
a. Which is the most important information to display on the report to encourage sites to provide
data?
A. Number of forms entered in the last week B. Expected versus actual forms entered C. List of outstanding forms D. Total number of forms entered to date
Answer: C Explanation:
In managing site data timeliness, the most actionable and effective tool is a report listing all
outstanding (missing or incomplete) CRFs.
According to GCDMP (Chapter: Communication and Study Reporting), Data Managers must provide
site-level performance reports highlighting:
Outstanding CRFs not yet entered,
Unresolved queries, and
Pending data corrections.
Such reports help sites prioritize and address data gaps efficiently.
Option A and D are historical metrics without actionable context.
Option B gives a general overview but lacks specific site-level actionability.
Hence, option C (List of outstanding forms) provides the clearest and most motivating feedback to
sites for timely data entry and query resolution.

Question # 6
For clinical investigational sites on an EDC trial, which of the following archival options allows
traceability of changes made to data?
A. Storing the computer used at the clinical investigational site B. Paper copies of the source documents C. PDF images of the final eCRF screens for each patient D. ASCII files of the site's data and related audit trails
Answer: D Explanation:
Regulatory agencies such as the FDA and ICH require that electronic data be retained in a format that
preserves audit trails and traceability.
While PDF images (option C) provide a static representation of data, they do not preserve the
underlying audit trail (i.e., who changed what, when, and why). The ASCII data files with
corresponding audit trails (option D) provide complete transparency and comply with 21 CFR Part 11
and GCDMP archival standards.
Option A (storing computers) is unnecessary and impractical, and Option B (paper source
documents) are site records, not system archives.
Hence, option D is correct ” ASCII data files with audit trails meet traceability and compliance
standards.

Question # 7
A Data Manager is designing a CRF for a study for which the efficacy data are not covered by the
current SDTM domains. Which search should the Data Manager do?
A. Use controlled terminology covering the needed concepts B. Work with the study team to define new data elements C. Search for relevant data element standards D. Advise the study team not to collect the data
Answer: C Explanation:
When existing SDTM (Study Data Tabulation Model) domains do not cover specific efficacy data, the
best practice is to first search for relevant data element standards that may be available through
CDISC CDASH (Clinical Data Acquisition Standards Harmonization) or other recognized industry
standards.
Per GCDMP (Chapter: Standards and Data Integration), Data Managers must ensure that new CRF
elements are consistent with standardized definitions, controlled terminology, and data models to
support interoperability, future analysis, and regulatory submission.
If no existing standards exist, only then should the Data Manager collaborate with the study team to
define new elements ” but standard searches always come first.
Thus, option C is correct ” search for relevant data element standards ensures alignment with CDISC
best practices and regulatory expectations.

Question # 8
ePRO data are collected for a study using study devices given to subjects. Which is the most
appropriate quality control method for the data?
A. Programmed edit checks to detect out of range values after submission to the database B. Manual review of data by the site study coordinator at the next visit C. Data visualizations to look for site-to-site variation D. Programmed edit checks to detect out of range values upon data entry
Answer: D Explanation:
When electronic patient-reported outcomes (ePRO) devices are used, data are captured directly by
subjects through validated devices and transmitted electronically to the study database. To ensure
real-time data quality control, programmed edit checks should be implemented at the point of data
entry ” that is, as subjects input data into the device.
According to Good Clinical Data Management Practices (GCDMP, Chapter: Data Validation and
Cleaning), front-end programmed edit checks are the optimal method to prevent entry of invalid or
out-of-range values in ePRO systems. This helps maintain data accuracy at the source, minimizing
downstream queries and data cleaning workload.
Options A and B involve post-submission or manual review, which is less efficient and not compliant
with the principle of first-pass data validation. Option C (visualization) is a valuable secondary QC
method for trends, but not for immediate data validation.
Therefore, option D is correct ” programmed edit checks upon data entry ensure immediate validation and higher data integrity.

Question # 9
Which action has the most impact on the performance of a relational database system?
A. Entering data into the database from CRFs B. Loading a large lab data file into the database C. Executing a properly designed database query D. Making updates to data previously entered into the database
Answer: B Explanation:
In a relational database system used in clinical data management, performance refers to how
efficiently the system processes transactions, retrieves data, and handles large volumes of
information without delay or data integrity issues. Among the listed options, loading a large lab data
file into the database (Option B) has the most significant impact on database performance.
According to the Good Clinical Data Management Practices (GCDMP, Chapter on Database Design
and Build), the bulk data load process ” such as importing large external datasets (e.g., central lab
data, ECG results, or imaging metadata) ” can be computationally intensive. This process engages
the databases input/output (I/O) subsystem, indexing mechanisms, and transaction logs
simultaneously, often locking tables temporarily and consuming significant memory and processing
resources.
Unlike standard CRF data entry (Option A) or record updates (Option D), which are incremental and
typically processed in smaller transactional batches, bulk loading operations handle thousands or
millions of rows at once. If not optimized (e.g., via staging tables, indexing strategies, or commit
frequency control), such operations can degrade system performance, slow down concurrent user
access, and increase the risk of transaction failure.
Executing a properly designed query (Option C) can also be resource-intensive depending on data volume and join complexity, but when queries are properly optimized (using indexed keys, efficient
SQL joins, and selective retrieval), their impact is generally controlled and transient compared to
large data imports.
Therefore, as outlined in the GCDMP Database Design and Build and FDA Computerized Systems
Guidance, the most performance-impacting activity in a relational database is bulk loading large
external datasets, making Option B the correct answer.

Question # 10
A Data Manager is asked to manage SOPs for a department. Given equal availability of the following
systems, which of the following is the best choice for managing the organizational SOPs?
A. Document management system B. Customized Excel spreadsheet C. Learning management system D. Existing paper filing system
Answer: A Explanation:
The best choice for managing Standard Operating Procedures (SOPs) in a compliant and auditable
manner is a Document Management System (DMS).
According to the GCDMP (Chapter: Regulatory Requirements and Compliance) and ICH E6 (R2), SOPs
must be version-controlled, securely stored, retrievable, and auditable. A validated DMS supports
controlled access, document lifecycle management (draft, review, approval, and archival), and electronic audit trails, ensuring full compliance with FDA 21 CFR Part 11 and Good Documentation
Practices (GDP).
While Learning Management Systems (C) track training, they are not intended for document control.
Spreadsheets (B) and paper systems (D) cannot provide adequate version tracking, access security, or
audit capability required for regulatory inspection readiness.

Question # 11
For ease of data processing, the study team would like the database codes for a copyrighted rating
scale preprinted on the CRF. What is the most critical task that the CRF designer must do to ensure
the data collected on the CRF for the scale are reliable and will support the results of the final
analysis?
A. Consult the independent source and determine database codes will not influence subject responses. B. Consult the study statistician regarding the change and determine that database codes will not influence the analysis. C. Consult the independent source of the rating scale for approval and document that continued validity of the tool is not compromised. D. Complete the requested changes to the instrument and ensure the correct database codes are associated with the appropriate responses.
Answer: C Explanation:
When using a copyrighted or validated rating scale (e.g., Hamilton Depression Scale, Visual Analog
Pain Scale), any modification to the original instrument, including preprinting database codes on the
CRF, must be approved by the instruments owner or licensing authority to ensure the validity and
reliability of the instrument are not compromised.
According to the GCDMP (Chapter: CRF Design and Data Collection), validated rating scales are
psychometrically tested tools. Any visual or structural modification (such as adding codes, changing
layout, or rewording questions) can invalidate prior validation results. Therefore, the CRF designer
must consult the independent source (copyright holder) for approval and document that the validity
of the tool remains intact.
Merely consulting statisticians (option B) or verifying database alignment (option D) does not ensure
compliance. Thus, Option C ensures scientific and regulatory integrity.

Question # 12
During a database audit, it was determined that there were more errors than expected. Who is
responsible for assessing the overall impact on the analysis of the data?
A. Data Manager B. Statistician C. Quality Auditor D. Investigator
Answer: B Explanation:
The Statistician is responsible for assessing the overall impact of data errors on the analysis and study
results.
According to the Good Clinical Data Management Practices (GCDMP, Chapter: Data Quality
Assurance and Control) and ICH E9 (Statistical Principles for Clinical Trials), while the Data Manager
ensures data accuracy and completeness through cleaning and validation, the Statistician determines
whether the observed data discrepancies are statistically significant or if they may affect the validity,
power, or interpretability of the studys outcomes.
The Quality Auditor (C) identifies and reports issues but does not quantify analytical impact. The
Investigator (D) is responsible for clinical oversight, not statistical assessment. Thus, after a database
audit, the Statistician (B) performs a formal evaluation to determine whether the magnitude and
nature of the errors could bias results or require reanalysis.

Question # 13
What additional task does the site study coordinator role perform when utilizing an EDC application
compared to paper CRF?
A. Resolving queries B. Data entry C. Data curation D. Medical record abstraction
Answer: B Explanation:
In paper-based trials, site staff (e.g., study coordinators) record data manually on paper Case Report
Forms (CRFs), which are later transcribed by data entry personnel into an electronic database.
However, in EDC-based studies, the site coordinator is directly responsible for entering data into the
EDC system. This eliminates the need for centralized double data entry and shortens data cleaning
timelines.
The GCDMP (Chapter: Electronic Data Capture Systems) states that EDC systems shift certain tasks,
including data entry, initial query response, and source verification preparation, to the site level. Yet,
data entry remains the most significant additional responsibility compared to paper-based studies.
Option A (Query resolution) is performed in both EDC and paper-based systems.
Option C (Data curation) is typically a Data Management function.
Option D (Medical record abstraction) is part of source documentation, not specific to EDC.
Thus, option B (Data entry) is correct ” it is the additional site coordinator duty unique to EDC
environments.

Question # 14
It has been identified that ten adverse events were not reported in the trial prior to the database
lock. What action should be taken to determine the next step?
A. Get the AE data entered immediately so the database can be locked again. B. Evaluate the potential effect of the omission on the validity of the safety and efficacy analysis. C. Notify upper management immediately so the monitor can contact the site. D. Check the data from all sites again before relocking the database.
Answer: B Explanation:
When adverse events (AEs) are discovered after a database lock, the appropriate first step is to
evaluate the impact of the missing data on the integrity, safety analysis, and regulatory validity of the
study results.
According to GCDMP (Chapter: Data Quality Assurance and Control), any post-lock data discovery
requires a root cause assessment and impact analysis before deciding whether to unlock the
database. The key question is whether the missing AEs:
Affect primary safety endpoints,
Introduce bias in safety reporting, or
Alter efficacy conclusions.
Based on the assessment, the Data Management and Biostatistics teams determine if unlocking and
correction are justified. Simply entering data immediately (A) or repeating checks (D) without
analysis may violate data control procedures.
Hence, option B is correct ” the first step is to assess the impact on data validity and analysis.

Question # 15
Which of the following tasks would be reasonable during a major upgrade of a clinical data
management system?
A. All of the data formats in the archive should be updated to new standards. B. The ability to access and read the clinical data archive should be tested. C. The data archive should be migrated to an offsite database server. D. All of the case report forms should be pulled and compared to the archive.
Answer: B Explanation:
During a major system upgrade, it is critical to verify that archived data remain accessible, readable,
and intact following the implementation.
According to the GCDMP (Chapter: Database Lock and Archiving), regulatory requirements such as 21
CFR Part 11 and ICH E6(R2) mandate that archived data must remain retrievable in a human-readable
format for the duration of retention (often years after study completion).
Therefore, as part of validation and verification testing, organizations must confirm that existing
archives can still be accessed using the upgraded system or compatible tools.
Option A: Updating archive formats could alter original data integrity (noncompliant).
Option C: Migration offsite is an IT infrastructure task, not directly tied to the upgrade process.
Option D: Comparing CRFs to archives is unnecessary unless data corruption is suspected.
Hence, option B (testing archive accessibility) is the correct and compliant approach. Reference (CCDM-Verified Sources):
