Process of taking a method and evaluating the ability to provide accurate and reproducible results.
27
Outline ISO 17025 s. 7.2.2

33
What is ISO/IEC 17020 used for?
For forensic practitioners that do not conduct analytical scientific testing using instrumentation and equipment found in a traditional science lab.
34
What factors does the ISO/IEC 17020 standard focus on?
Impartiality Independence Confidentiality Item selection Item handling
35
True or false: Firearms/toolmarks can be accredited under either ISO/IEC 17020 OR 17025?
True
36
Outline the six steps of the accreditation process.
Develop quality management system Application Pre-assessment Assessment Response Surveillance
37

Quality manager but quality is everyone's responsibility
38
Describe the pre-assessment stage of the accreditation process.
External group assesses how you're expected to do and then addresses issues
39
Outline the assessment stage of the accreditation process.
~ 1 week Each section's standards are evaluated Then identify findings
40
How long does accreditation certification last?
4 years
41
Describe the surveillance stage of the accreditation process/
Individual assessments made annually
42
What information is provided to assessors? (6)

43
Outline the accreditation assessment. (7)

What are the downsides to accreditation?
cost complicated documentation Not a panacea that prevents every problem
45
Why are proficiency tests often used in court?
To help establish expertise and reliability of examiner
46
What two main questions does proficiency testing aim to investigate?
Is the testing method reliable? How often does a particular analyst make an error?
47
Where do you get proficiency testing from?
Internal External
48
Do external proficiency test providers have to be accredited?
Yes
49
What is blind proficiency testing?
Submitted as an authentic case Test recipients don't know it's a test

No person shall, in laboratory, conduct a test to which this section applies, unless, a) the lab is accredited, by an accrediting body prescribed by the regulations, to a prescribed general standard; and b) if the test is a prescribed test, the laboratory is accredited, by an accrediting body prescribed by the regulations, to a prescribed standard for that test.

No
61
What is root cause analysis?
Tool designed to help identify not only what happened, how it happened, but also why it happened.
62
Who can use root cause analysis?
May be used in many different areas
63
What did the National commission on forensic science say about root cause analysis?
It is recommended that appropriate root cause analysis protocols for all forensic science service providers or forensic science medical providers be adopted.
64
What is the important thing to remember about root cause analysis?
Purpose is learning, not punishment
65
What are the 5 classifications of an error during root cause analysis?
Catastrophic Major Moderate I Moderate II Minor
66
Describe the 'catastrophic' classification of root cause analysis.
Systemic errors in procedure(s) that affect several outcomes or reported results; intentional misconduct by personnel
67
Describe the 'Major' classification of root cause analysis.
Casework error that affects outcome or reported result. Could include potential problems that may affect the reliability or accuracy of a test procedure or serious negligence by personnel.
68
Describe the 'Moderate I' classification of root cause analysis.
Clerical error - Does affect result but corrected during the review process prior to release of report
69
Describe the 'moderate II' classification of root cause analysis.
Clerical error nonconformity that does not affect outcome of reported result.
70
Describe the 'minor' classification of root cause analysis.
Clerical error - does not affect outcome or reported result.
71
What was the root and cultural cause analysis of report and testimony errors by FBI MHCA examiners?
Review by FBI started in 2012 of microscopic hair comparison after cases were highlighted where errors had occurred.
72
What was the main finding of the root and cultural cause analysis of report and testimony errors by FBI MHCA examiners?
The most important cause of report and testimony errors was that the MHCA examiners did not have sufficiently specific guidance
73
Outline the root cause model. (6)
Identify event Define the issue Collect and analyze data Identify contributing factors Implement corrective action Monitor the quality system
74
Why is the goal of root cause analysis to ask follow up questions five times/
Not all problems have a single root cause To uncover multiple root causes, the method must be repeated asking a different sequence of questions each time
75
What is the difference between quality control and quality assurance?
QC - Day-to-day things done to ensure quality of results QA - ensuring entire product is fit for purpose
