NAPT is bringing them back in-person Regional Interlaboratory Comparisons (ILCs) in response to strong demand from laboratories looking for hands-on proficiency testing opportunities.
Regional ILCs allow laboratories to participate in an Interlaboratory Comparison Proficiency Test, where participants perform measurements using their own standards and compare results with other laboratories in a structured, collaborative environment.
NAPT will host two Regional ILC events this summer in Minneapolis, MN and Greensboro, NC. To help us confirm scheduling and plan testing time blocks, interested participants are asked to sign up in advance.
