CPLP Re-Certification Requirements and Procedure

CPLP re-certification is required every three years, on each person’s 3-year anniversary of original certification or last re-certification. This preserves the integrity and status of the program by ensuring that a CPLP remains active in the field and is still qualified to hold the Certificate. 
CPLP recipients are individually notified by ISTA prior to their re-certification dates, and then the process must be completed within 90 days. If you do not re-certify, your present CPLP certification will be cancelled. The re-certification fee is US$150.  Advancement in CPLP level (from Technician to Technologist, or from Technologist to Professional) re-starts the certification period.

Note: CPLP Professional-Level recipients do not need to re-certify – the “Professional” achievement is a lifetime certification.
