This document prescribes the minimum requirements for the selection, development, validation, administration, evaluation, and documentation related to tests used by Forensic Service Providers (FSPs) for purposes of monitoring the proficiency of FSP personnel qualified to perform independent casework pertaining to examinations (Analysis, Comparison, and Evaluation) of friction ridge impressions. These requirements are applicable to tests developed internally by FSPs and tests obtained from external sources.

This document is meant to be used in conjunction with ASTM E3149 for Morphological Analysis. It describes the relative physical stability of facial features of adults when assessing the observed component characteristics within a single living subject as an aid to the facial comparison examiner. This document refers only to adult (post-pubescent) subjects and does not address the stability of features in children due to rapid developmental changes. It does not cover the entire comparison process. OSAC 2020-S-0002 STRP Report

This document provides guidelines for performing alcohol (ethanol) calculations. Guidance on calculations for retrograde extrapolation, forward estimations, minimum drinks consumed, and other typical situations are addressed. Recommendations are provided for evaluation of post absorptive stage, various specimen types, and population variances. Reporting of calculations is also addressed. This guideline is intended for an expert performing alcohol calculations, whether as an employee of a public or private laboratory, or as an independent forensic service provider. It applies to matters related to criminal and/or civil proceedings.

This standard provides requirements for the interpretation, comparison, and reporting of DNA data associated with control failures or contamination where re-testing is not performed. DNA data associated with a failed control or a contamination event may still be scientifically valid and may be relevant to an investigation. These standards may be applied to any type of forensic DNA testing technology and methodology when conducted in an accredited forensic laboratory. OSAC 2020-S-0004 STRP Report

These standards shall be used by forensic laboratories which, as part of their casework data analysis processes, are manually making: a) binary determinations that a peak in an electropherogram is not the result of random fluctuations intrinsic to the analytical process; rather it is a peak that is representative of allele(s) or artifact(s); and b) binary determinations that allele drop-out did not occur. This standard is applicable to forensic STR DNA typing performed on electrophoresis platforms.
This document provides minimum requirements for evaluating measurement uncertainty for quantitative measurements in forensic toxicology. The document is for both testing and calibration activities and provides direction on evaluation of components, bias, calculations, and reporting. While the document addresses calibration of breath alcohol measuring instruments, it does not address evaluating measurement uncertainty for breath alcohol testing. This topic will be covered in a different document.
This standard covers the requirements and recommendations for analysis and selection of DNA sequences retrieved from the National Center for Biotechnology Information’s GenBank and their subsequent use as reference material for taxonomic identification of wildlife. This standard does not cover the use of DNA sequences from other public sequence databases (e.g., BOLD, UNITE), the protocol for downloading sequences from GenBank for inclusion in in-house databases, or the use of custom BLAST searches against GenBank. However, the criteria can be conceptually applied to other sequence databases.
This document is intended to be applicable to all reports where bloodstain pattern analysis (BPA) classifications or BPA case conclusions are rendered.
This guide provides procedures describing specific photography and lighting techniques for documenting autopsies. These photographs serve as a permanent record of the autopsy, related evidence, and findings. This standard cannot replace knowledge, skills, or abilities acquired through education, training, and experience, and is to be used in conjunction with professional judgment by individuals with such discipline-specific knowledge, skills, and abilities. This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
