The content of the examination is based on tasks performed by CSFAs nationwide. A job analysis survey was conducted to identify specific tasks related to the frequency and importance of Surgical First Assistants nationwide. The results of the job analysis were used to develop the content outline for the examination, which is evaluated on a prescribed schedule to ensure that the overall examination content reflects current surgical first assistant practice.
You will have four (4) hours to complete your examination. All questions on the examination are multiple choice. You will be allowed to take a break whenever you wish, but you will not be allowed additional time to make up for time lost during breaks. You will not be able to return to questions previously answered after taking a break. The location of breaks is governed by the proctor and you will not be allowed to leave the building during a break.
The CSFA examination consists of 175 multiple-choice questions, 150 of which are scored. The 25 pretest items (unscored) are randomly distributed throughout the examination for the purpose of analysis and statistical evaluation.
Passing Score
The passing score is the minimum number of questions that must be answered correctly. The current passing score for the CSFA examination is 99 (recently increased from 97) of the 150 scored questions. Score reports are provided to all candidates who take the examination.
How Did We Set The Passing Score?
After the job analysis and one round of test development based off the updated examination content outline has been completed a separate committee of SMEs is convened, the NBSTSA Standard Setting Committee.
Standard setting, or cut score setting, is a critical step in the test development process, which occurs after job analysis. It involves determining the minimum score a candidate must achieve to be considered competent in the skill or knowledge area the test is measuring. In simple terms, this is setting the passing score for the test.
The NBSTSA standard-setting meetings usually take one day per examination and occur in person. Standard-setting meetings occur only at the end of our job analysis cycle process, only once every 4-5 years.
The process begins with a panel of subject matter experts (SMEs) who are thoroughly familiar with the test content and the target population's abilities. For NBSTSA, these experts are always asked to remember that our examinations are for entry-level professionals.
These SMEs review each test item and judge the item’s difficulty level. They estimate the probability that a minimally competent candidate would answer the item correctly. This process is always facilitated by a psychometrician who ensures that the panel’s judgments are statistically sound and defensible.
Once the SMEs have rated all the items, their ratings are aggregated to form an initial recommended cut score based on an analysis of the statistical data provided by the ratings. This score is then reviewed and adjusted as necessary based on a variety of considerations, such as the consequences of false positives (passing candidates who are not truly competent) and false negatives (failing candidates who are competent), the need for consistency with other tests in the same program, and legal and regulatory requirements.
The NBSTSA Board of Directors meets with the psychometrician, and any other necessary test development team members, to be presented with the findings of the standard-setting committee after the standard-setting meeting has been completed. The Board has final approval and oversight of the passing score (cut score) for all NBSTSA examinations.
Once the cut score is set, it is announced concurrently with the launch of the new examination forms.
After the cut score is set, it’s not the end of the process. The cut score should be periodically reviewed and possibly adjusted to account for changes in the test content or the abilities of the test-taking population. This ensures the examination remains both valid and fair over time. NBSTSA typically only changes the cut score during standard setting following an examination development cycle after a job analysis.
Standard setting is a complex, iterative process that requires a combination of expert judgment and statistical analysis. Ensuring that certification tests are fair, valid, and valuable in their intended contexts is crucial.
