The CPH exam results uses a scaled scoring. Candidates can score between 300 and 800. A score of 500 is needed to pass the exam.

Starting on August 1, 2024 score reports will show scaled scores instead of raw scores. A scaled score is a representation of a candidate’s total number of right answers (raw score) transformed to a uniform and standardized scale. Scaled scoring is a certification industry best practice for reporting high stakes exam scores. It provides a consistent scale of measurement from one exam session to the next; the same scaled score signifies the same degree of knowledge. This means that scores from different versions of the exam indicate the same level of performance regardless of which exam form a candidate has received. This will take into account the potential difference in difficulty between exam forms.

Testing Options: In-Person & Online

Content Outline Update

Testing under the new content outline will begin on August 1, 2024.

Certification boards update the content outline every five to seven years through a Job Task Analysis (JTA) process. This ensures that CPH candidates are tested on current tasks performed in the field.

The difficulty level of the CPH exam varies yearly. The testing committee adjusts for fluctuations in difficulty using anchor questions. The passing score is set to ensure competent examinees pass. The same process will apply under the new content outline.

The level of competence needed to pass the exam will not change. However, starting on August 1, 2024, score reports will show scaled scores instead of raw scores. Scaled scoring standardizes scores across different exam forms, indicating the same level of performance regardless of the exam version.

Candidates testing in August 2024 will not receive instant results as the new passing score is set. Once the passing score is determined, results will be notified. Schools and programs will receive scores for their students and alumni testing during this period simultaneously.

The content changes are not significant, and most candidates will perform similarly under both outlines. Take the exam when you feel most prepared.

The changes are mostly a reorganization of content and more succinct descriptions of tasks under each domain. The weighting of each domain has changed from 10% each to between 8% and 12%, representing about four additional or fewer questions per domain.
