Pharmacy Technician Certification Exam (PTCE®) scoring policies can be found in the PTCB Candidate Guidebook.
Per the Exam Challenges section of the PTCB Candidate Guidebook, "the primary mechanism for candidates to challenge the accuracy of exam content on the PTCE is to comment within the exam itself. Candidates can comment on any item during the exam. PTCB and subject-matter experts review all candidate comments prior to the release of official scores. In extremely rare circumstances the review of candidate comments may result in candidates receiving an official exam result that differs from the preliminary result provided at the end of the exam.
Certification candidates who wish to challenge the accuracy of exam content after the exam is completed (i.e., did not comment within the exam), must submit their challenge according to the Certification Appeals Procedures within 30 days following the administration of the exam."
The Certification Appeals Procedures can be found in the PTCB Candidate Guidebook.
