If the applicant currently holds a high school subject-specific certificate, has a declared major in the subject area, and wishes only for the subject area to be extended to cover middle school grades, the applicant must make the appropriate payment through the KECS system. This type of modification may usually be processed in the EPSB office within 10 working days or less.

However, if the applicant is selecting an option that would entail the taking of a Praxis examination and transcript analysis, the cost will vary according to the examination cost. In addition to the applicable processing fee through the KECS, candidates are responsible for paying the cost of the Praxis examination(s) and $96.00 for the transcript analysis. The timeframe for obtaining these types of modifications varies according to when the applicant is able to take and receive scores for the applicable Praxis test(s). Once these scores are received, transcript reviews will take five working days, and then the EPSB office will process the certificate in 10 working days or less.
