EligibilityOnce an application is received candidates who are approved to take anexam are eligible for two testing wndows during a fine 9 month time priod. If you do not test during this timeperiod you must re-apply to the program and submit a new application fee.

ExaminationsA second comprehensive job analysiswas conducted in 2001 to account for thework performed by CSTs. The job analysis identified performance domains thatwere subsequently validated in a nationwide survey for each of the three leveis.

Leve and Leve III ExamsThe Level and III exams are closedbook exams of 175 multiple choice questions each; candidates are allowed fourhours for completion.Level II Exam

The Level II exam is a closed bookexam consisting of eight written problems that test the candidates ability toapply the knowledge and skills requiredfor each domain in simulted practicalsituations. The exam assesses the carididates ability to make decisions troubleshoot and make professional judgementsin situations too complex or critical totest in a hands-on practical examination; ndidtes are allowed four hours forcompletion. omins

If an applicant feels he she was wrongly denied certification, original or renewal,from the CCST program, then he/she has the right to appeal. Appeals

A lt appeals shall be in writing. The notice of appeal must be delivered to the Certification Board, addressedto the attention of the ISA Executive Director, by the close of business on the2lst day after the date of the notice of denied certification.2 The appeal should include the date the notice of denied certification was ceived and must state the reasons the applicant believes the denied certification was in error.3 The appeal should indicate whether or not the applicant requests a hearing. If a hearing is requested, the applicant must explain why a hearing isneeded identify the issues to be resolved at a hearing, list names of rspective witnesses, and identify documentation and other evidence to beintroduced at the hearing before the Board.4 The Chair of the Certification Board will select a three-member panel of theBoard to become the Review Panel, one of whom shall be appointed Chairand will be the final vote in the event of a tie during the ruling.

fi ProceduresA The Review Panel will review the appeal and any request for a hearing. he Review Panel will grant a hearing in connection with the appeal, if requested. Hearing The Chair of the Review Panel will determine the time and location of thehearing within 90 days after determination that a hearing is warrantedand will notify the applicant within the first 21 days. The applicant will benotified of the hearing time and location at least 20 days prior to the timedetermined for the hearing.a The applicant may be represented by counsel or represent him/herself atthe hearing. The applicant may offer witnesses and documents and maycross-examine y witness.b The Review Panel may consider any evidence it deems relevant withoutregard to strict application of legal rules of evidence.e The applicant is urged to submit a written brief four copies 10 days priorto the hearing to the Certification Board, addressed to the attention of theISA Executive Director, for distribution to the panel in support of his/herposition. However, written briefs are not required.d Deposition
