About the Registered Environmental Laboratory Technologist RELT exam
The RELT credential recently overhauled its microbiology and contamination protocols section, reflecting tightened EPA and state laboratory standards from 2023 onward. This refresh means test content now emphasizes chain-of-custody documentation and emerging contaminant detection methods that weren’t previously weighted as heavily, making preparation material from older study guides potentially incomplete for today’s examination.
