The ASCP Board of Certification uses the format of computer adaptive testing (CAT) for all certification examinations. With CAT, when a person answers a question correctly, the next test question has a higher level of difficulty. The difficulty level of the questions presented to the examinee continues to increase until a question is answered incorrectly. Then an easier question is presented. In this way, the test is tailored to the individual’s ability level.
Each question in the test bank is calibrated for level of difficulty and is classified by content area. The content area aligns with the examination specific content outline. The examinee must answer enough questions correctly to achieve a measure above the pass point in order to successfully pass the certification examination. There is no set number of questions one must answer to pass, nor is there a set percentage one must achieve to pass. If at the end of the exam the examinee’s score is above the pass point, then he or she passes the exam.
The examinations (with the exception of PBT and CTgyn) are scheduled for 2 hours and 30 minutes with 100 questions. The PBT examination is scheduled for 2 hours with 80 questions. The CTgyn examination is scheduled for 1½ hours with 50 questions.
Your preliminary test results (pass/fail) will appear on the computer screen. A notification to view your examination score post login will be emailed to you within four (4) business days after you have taken the examination provided all official transcripts verifying the appropriate degree have been received. Examination results cannot be released by telephone, to anyone.
Your official score report can be viewed online post login. It will indicate "PASS" or "FAIL" status and the scaled score on the total examination. All examination scores are reported in scaled score. A scaled score is mathematically derived (in part) from the raw score (number of correctly answered questions) and the difficulty level of the questions. Because each examinee has taken a different form of the examination, scaled scores are used so that tests may be compared on the same scale. The minimum passing score is 400. The highest attainable score is 999.
If you were unsuccessful in passing the examination, your scaled scores on each of the subtests will be indicated on this report as well. These subtest scores cannot be calculated to obtain your total score. These scores are provided as a means of demonstrating your areas of strengths and weaknesses in comparison to the minimum pass score.
