About the LPCB
The IAI CLPE is the industry-standard latent-print examiner credential, administered by the IAI Latent Print Certification Board (LPCB) since 1977. The certification has two phases: a written multiple-choice test on friction-ridge biology, ACE-V, development chemistry, AFIS, photography, pattern classification, and discipline standards (minimum 85% to pass) and a hands-on comparison test of 15 latent prints against known prints (12 correct identifications or exclusions required, zero erroneous conclusions, no inconclusives allowed). The fee is $300 for IAI members and $400 for non-members. Applicants need education-scaled full-time experience (2 years bachelor's, 3 years associate's, 4 years high school), 160 hours of LPCB-approved technical training, and 16 hours of court testimony training. Recertification is every 5 years with 80 professional development credits.

About the IAI CLPE Exam
The IAI Certified Latent Print Examiner (CLPE) is the leading U.S. credential for latent fingerprint examiners. Established in 1977 and administered by the IAI Latent Print Certification Board, it is a two-phase test: a written multiple-choice portion covering friction-ridge biology, ACE-V methodology, development chemistry, AFIS, and pattern classification (requiring 85% to pass), plus a hands-on comparison test of 15 latents against known prints (requiring 12 correct identifications or exclusions with zero erroneous conclusions). Recertification is required every 5 years with 80 professional development credits and periodic proficiency testing.

Frequently Asked Questions
What is the IAI CLPE certification?
The Certified Latent Print Examiner (CLPE) is the IAI's credential for latent fingerprint examiners, administered by the Latent Print Certification Board (LPCB). It has been issued since 1977 and is widely required or preferred for journeyman latent examiner positions in U.S. forensic laboratories.
What does the CLPE exam include?
The exam has two phases: a written multiple-choice test covering fingerprint history, friction-ridge biology, development techniques, ACE-V methodology, and pattern classification (minimum 85% to pass), and a hands-on comparison test of 15 latent prints against known prints (12 correct identifications or exclusions required with zero errors and no inconclusive findings allowed).
What is the passing score?
Applicants must score at least 85% on the written portion and reach 12 correct identifications or exclusions out of 15 on the comparison test with no erroneous conclusions.
How much does the CLPE cost?
The application fee is approximately $300 for IAI members and $400 for non-members, non-refundable, due at time of application. Recertification fees are the same.
What experience is required?
Experience requirements scale with education: bachelor's degree holders need 2 years of full-time latent print examination experience, associate's degree holders need 3 years, and high school diploma holders need 4 years. Internships and training time may count when 75% or more of duties are dedicated to latent print comparison.
What training is required?
Applicants must document 160 hours of LPCB-approved technical training plus 16 hours of qualifying court testimony training, all received within the 5 years preceding application. Internal training programs require LPCB pre-approval.
How long is the CLPE valid?
CLPE certification is valid for 5 years. Recertification requires 80 professional development credits earned during the most recent 5-year cycle and periodic proficiency testing.
Are inconclusive findings allowed on the comparison test?
No. The CLPE comparison test materials are selected so that every latent can be resolved as an identification or an exclusion. Inconclusive conclusions are not permitted on the test, though inconclusive remains a valid reporting conclusion in operational casework under OSAC standards.
Is there a sponsor or endorsement requirement?
Yes. Applicants must be employed (or have been recently employed) in a position requiring latent print examination, and the application requires documentation of qualifying casework and approval from the candidate's agency or sponsor.
