ACI Quality Assurance & Compliance 2 — Questions and Answers
Question 1: Which accreditation standard is specifically designed for forensic science laboratories and is commonly required by law enforcement agencies?
- ISO 9001
- ASCLD/LAB (now ANAB) (Correct answer)
- CMMI Level 3
- SOC 2 Type II
Correct answer: ASCLD/LAB (now ANAB)
ASCLD/LAB (now merged into ANAB) is the primary accreditation body for forensic science laboratories recognized by law enforcement.
Question 2: During a forensic lab audit, a reviewer finds that an examiner failed to document a deviation from the standard operating procedure. What is the most appropriate corrective action?
- Discard all evidence processed during that period
- Issue a corrective action report and update training records (Correct answer)
- Immediately suspend the examiner without investigation
- Retroactively alter the case notes to reflect proper procedure
Correct answer: Issue a corrective action report and update training records
A corrective action report documents the deviation, identifies root cause, and updates training to prevent recurrence without destroying valid work.
Question 3: What is the primary purpose of conducting proficiency tests on forensic examiners?
- To rank examiners for promotion decisions
- To demonstrate examiner competency and verify consistent, accurate results (Correct answer)
- To satisfy insurance requirements for the laboratory
- To measure how quickly examiners complete cases
Correct answer: To demonstrate examiner competency and verify consistent, accurate results
Proficiency testing evaluates whether examiners produce accurate, reliable results consistent with established standards.
Question 4: An investigator is asked to testify about findings from a forensic tool that has never been validated by the lab. Under quality compliance principles, what should the investigator do?
- Testify but omit the tool name from the report
- Refuse to use or testify about results from an unvalidated tool (Correct answer)
- Use the tool and note the lack of validation in testimony
- Ask a colleague to validate it verbally before court
Correct answer: Refuse to use or testify about results from an unvalidated tool
Quality standards require that all forensic tools be formally validated before results are used in case work or court testimony.
Question 5: Which document type defines the step-by-step processes that forensic examiners must follow to ensure consistency and reproducibility?
- Incident Response Plan
- Standard Operating Procedure (SOP) (Correct answer)
- Chain of Custody Form
- Evidence Receipt Log
Correct answer: Standard Operating Procedure (SOP)
SOPs provide detailed, standardized instructions that ensure all examiners perform analyses the same way, supporting reproducibility and quality.
Question 6: When a forensic laboratory's quality manual is reviewed, it should address all of the following EXCEPT:
- Personnel qualifications and training
- Equipment calibration and maintenance
- Case pricing and billing schedules (Correct answer)
- Document control and record retention
Correct answer: Case pricing and billing schedules
A quality manual covers technical and procedural standards; billing and pricing are administrative functions not part of quality compliance documentation.
Question 7: In the context of digital forensics QA, what is a 'blind verification'?
- A second examiner reviews the evidence without knowing the original examiner's conclusions (Correct answer)
- The lab hides the evidence location from the examiner
- Software analysis performed without the examiner viewing the screen
- A review conducted without access to the original evidence
Correct answer: A second examiner reviews the evidence without knowing the original examiner's conclusions
Blind verification prevents confirmation bias by having an independent examiner reach conclusions without knowledge of the first examiner's findings.
