Proficiency testing requirements

In order to become ELAP certified, your laboratory must demonstrate proficiency for all requested analytes listed in Certification Manual Item 316 below.  

For continuing accreditation, achieve passing scores in at least two (2) of three (3) consecutive proficiency tests (PT). The PT study close dates successive PT samples for a field of accreditation must be at least five (5) months apart and no longer than seven (7) months apart from the prior study.

Also, at least one of the scores must be less than six (6) months old. Corrective action or supplemental PTs must be at least seven (7) days from the close date of the prior study.

Therefore, you may take any combination of the following actions:

  1. Request that the TNI Accredited providers send test scores from analyses performed within the previous eighteen (18) months on samples directly to the ELAP Office.
  2. Purchase samples of each requested Field of Proficiency Testing compound from one of the TNI Accredited providers and have the provider submit your scores directly to the ELAP Office.
  3. Wait until the analytes are tested in the next regularly scheduled NYS DOH Wadsworth Center PT Program study found in Item 310 of the Certification Manual.

Scores (evaluation reports) are required to be released within twenty-one (21) days after the study's close date. Changes to a lab's accreditation status are acted on within 60 calendar days of the release date of the test scores to the ELAP Office.
