Forensic DNA analysts undergo extensive training to bridge the gap between their academic studies and the practical demands of crime laboratory work. However, with training programs often spanning up to two years, both new hires and forensic laboratories face significant challenges in balancing onboarding with the urgent need for casework. Recognizing this, Dr. Kelly Elkins and her team at Towson University conducted a comprehensive survey of DNA analyst training programs across U.S. forensic laboratories.
In this interview, Dr. Elkins shares the findings from this survey, exploring the resources, methodologies, and challenges shaping DNA analyst training today. From the critical role of hands-on practice to the need for more emphasis on troubleshooting and validation, her insights provide a roadmap for laboratories aiming to enhance their training programs while addressing resource constraints and workforce demands.
What initially led you and your team to conduct this survey on DNA analyst training in U.S. forensic laboratories? What gaps or needs in training inspired the project?
We were interested in training for a few reasons. First, new graduates of forensic programs reported long training periods of up to two years even after completing Masters degrees in Forensic Science. We wanted to understand the content and coverage the forensic laboratories are seeking and are assigning in training to help streamline the process. Long training programs have unintended ramifications for trainees and laboratories. University modules and courses should closely align to the content and terminology needed in testimony and sample analysis experience needed in the laboratory. Appropriate focus will alleviate the need for the laboratory to redo or retrain everything graduates learned in a course.
Secondly, students attend college and university for myriad reasons but one of the most common reasons students study forensic science is to get a job in a forensic science laboratory where they seek to make a difference. After four or six years (or more) of postsecondary education, students want to finally be able to make a difference and contribute to casework testing such as rape kit testing. They do not want to be hired and told it will be two more years of study and waiting to finally contribute to the efforts to make our communities safer. Additionally, forensic laboratory directors also want new hires to progress in training because they have backlogs and cases to test. Better understanding academic and laboratory capabilities and needs will allow better alignment of curriculum and laboratory training activities and hopefully reduce the time new hires spend in training.
The survey highlights a wide variety of resources that trainees are encouraged to study, from foundational books to laboratory-specific SOPs. Were there any resources that stood out as particularly essential or universally used across labs?
Numerous training resources are used especially Dr. John Butler’s books, Advanced Topics in Forensic DNA Typing: Methodology, Advanced Topics in Forensic DNA Typing: Interpretation, and Fundamentals of DNA Typing, but also Forensic DNA Typing. Other frequently used resources include training manuals, SOPs, quality assurance documents, journal articles, books by other authors especially for statistics and probabilistic genotyping, manufacturer’s manuals, ANSI/ASB standards, SWGDAM documents, OJP training resources and the NRC report.
Hands-on practice, shadowing, and readings were among the top training activities mentioned by respondents. In your experience, what makes these training methods so effective for new DNA analysts?
New hires are expected to know the theory and literature in their respective sections of the laboratory either prior to hire or following study and training. Most new hires need to additionally study and this is where readings are so important. Each laboratory has its own policies and procedures; new analysts need to learn these so shadowing is essential. One to one training is provided to new analysts in training. This is effective as trainees are provided individualized instruction and immediate feedback to develop and perfect their skills. To become a qualified analyst, each new hire must progress through hands-on practice, documented training samples and competency testing.
One area labs indicated they’d like to spend more time on in training is troubleshooting. How do you think labs could address this, and what are some specific challenges in troubleshooting that DNA analysts encounter?
We heard this from many respondents and interviewees. Trainees could be included in routine weekly freezer and instrument checks, software updates, validation of new instruments and tools, and troubleshooting errors and problems in testing that are noted or arise. Shadowing these activities will give the trainees insight into the decision making, steps and documentation that laboratory staff perform when troubleshooting as well as who they call for instrument maintenance authorizations and repairs. The challenge is taking trainees away from scheduled training tasks and new analysts away from casework. Incidents and issues that arise and warrant troubleshooting occur with little warning or regard to schedules.
Many labs reported using quizzes, oral exams, and final assessments to evaluate competency. In your opinion, are there specific assessment methods that seem particularly effective in gauging a trainee's readiness for casework?
Frequent quizzes, cumulative oral exams, and final written assessments are all useful tools for gauging a trainee’s content knowledge and ability to explain concepts. Mock case sample processing and testimony best simulate the tasks and roles of the forensic scientist and readiness for casework.
In terms of training coordinators, it sounds like their role varies significantly depending on the lab’s structure. Could you share any best practices for labs that have successfully implemented a training coordinator to support DNA analyst development?
The laboratory training and work assignment structure varies significantly depending on the laboratory structure. A forensic scientist may have many titles and roles including Forensic Scientist, Analyst, Technical Lead, Unit Supervisor, and Training Coordinator. Having a training coordinator is a best practice. The training coordinator creates or compiles and updates the training curriculum and reading list, reporting forms, practice and competency samples, conducts training modules, and monitors training daily activities and progress. The training coordinator writes and administers assessments including quizzes, examinations, oral examinations, and mock case testing and court testimony. As needed, the training coordinator will create a retraining plan and experiences. Training coordinators ensure that trainees have specific training activities each work day which makes training progress more efficiently.
For labs that lack the resources for an in-house training coordinator, what advice would you give to leaders or mentors who are balancing training with their casework responsibilities?
The training program needs to be organized with checklists and the trainees need to be self-directed and ask for help when they need it. Many laboratories are willing to share their training materials and reading lists with other laboratories developing their training programs. Scheduling a weekly check-in with mentees is another best practice.
Your survey noted that labs wanted to focus more on validation and root cause analysis in their training. How might labs integrate more of these critical skills into the training process, even with resource constraints?
The use of screenshots and previously documented troubleshooting and application of root cause analysis procedures could be used without additional consumable resources. Laboratories still need to schedule time for this training and refreshers but many laboratories are holding a day or afternoon a month for this.
Finally, based on the survey results, what do you see as the next steps for supporting and enhancing DNA analyst training across U.S. forensic labs? Are there areas where additional guidance or standardization could benefit the field as a whole?
There is a new Google group for trainers to share materials and best practices and we have launched a new website to host curriculum materials we have created for use in teaching and training.
