Once enough examination exam content has been developed to fulfill the test specifications, examination exam assembly can take place. This step also requires the participation of an expert panel.
During this process, the panel will select selects the best items in each area of the test blueprint. Should any final modifications be required in advance of publishing the exam form, it will likely occur during this meeting.

Building the Exam Versions
Building a high-stakes exam typically involves selecting questions items that fit certain criteria and placing them appropriately within the exam, much like a complicated jigsaw puzzle. Typically, subject matter experts spread a stack of questions items on a conference table and manually select the questions items based on criteria such as question item quality, content area, cognitive complexity level, question item difficulty, and category type. Due to the inefficient and error-prone nature of this process, organizations can look to online tools such as Exam Design’s ExamDeveloper for assistance.
Often times multiple versions of exams are built simultaneously, where different questions items are selected for each version so that examinees candidates do not always receive the same exam version. When this happens, the difficulty of each exam version is calculated to ensure examinees candidates are not unfairly penalized by receiving a more difficult exam version.
There are several important considerations when determining how many versions of an exam are needed:
How many examinees candidates are being tested annually? With an annual examinee candidate population of 500, fewer versions are required than if the annual examinee candidate population is 10,000. A general rule of thumb is to use a new exam form after it has been administered to 1,000 examineescandidates, or at least annually.
How often can examinees candidates retake the exam? Examinees Candidates who fail a high-stakes exam are often given a chance to retake it after a waiting period (usually 6-12 months after the initial administration). Programs with a short waiting period require additional exam versions to reduce the chance of examinees candidates taking the same exam version.
What are the consequences of failing the exam? Exams with substantial consequences for failure will increase the likelihood that dishonesty or cheating may occur. Exams that preclude individuals from practicing in a particular field carry the greatest consequences for failure. Other examples include those that tie compensation to performance on the exam. In these cases, it is important to build and administer multiple versions of the exam to reduce the likelihood of cheating or other dishonest behavior.
Job/Task Analysis Specifications. At a minimum, high-stakes exams need to should be built according to the tasks, knowledge, and skills identified through the JTA process. In order to establish content validity for the exam, a systematic process must be used to select questions items based on the relative importance, criticality, and frequency of the duties and requirements for competent job performance. In other words, job tasks which are twice as important or frequently performed in comparison to others should receive twice as much weight on the exam.
Cognitive Complexity Level. Organizations can also choose questions items so that there is not an overwhelming majority of questions items which target one level of cognitive complexity. Typically, this is used to prevent the exam from consisting of predominately recall-based questions, as question- item writers find that type of item the easiest to develop.
Content Categories. Organizations may also choose to identify a separate set of content categories to build a two-dimensional matrix of content area by tasks performed. As an example, imagine an exam for veterinary medicine which seeks to evaluate competence in regards to the following professional tasks: gathering patient histories, conducting assessments, diagnosing symptoms, and developing treatment plans. Questions Items could be selected using a two-dimensional matrix according to species so that there would be three questions items related to gathering patient histories for dogs, three questions items related to developing a treatment plan for cats, and so on.
Keywords. The exam also can also be assembled according to keywords. Keywords are typically important phrases or concepts that are contained within the questionitem. Organizations typically use keywords as a filtering mechanism when building exams so that there are not several questions items covering the exact same concepts on an exam version.
Difficulty. Another factor used in building exams is a question’s an item’s difficulty. Organizations should select questions items such that the difficulty of one exam version is set to be equal to that of other versions. Difficulty can be measured using a variety of statistical techniques. One of the simplest is the percentage of people who answered the question item correctly. This method is useful when question item difficulty is already known through the use of those questions items during previous exam administrations.
When reviewing an assembled examinationexam, ensure that each item is independent. That is, ensure that knowing the answer to one item will not allow one to answer another questionitem.
Reviewing a Draft
It is also at this stage that substantial review is required. Recall the types of review we discussed before in the Peer Review Process section:
However, in this case, we will add a fifth type to the list: Format Review
Format review is required to confirm that the display of the examination exam content is satisfactory. For example, on a paper and pencil examinationexam, this review will confirm confirms that the items are laid out correctly on the pages. For an examination exam being delivered via computer, one would want to confirm that all items are displayed correctly on the screen and that any graphics or attachments are shown clearly.
Scored versus Unscored Items: Depending on the equating method that is chosen for the program, your examination exam may have a mix of scored and unscored items. Scored items mean that the examineecandidate's response to an item, right or wrong, counts toward his or her final score. In some higher stakes examination exam programs, only items that have been tested previously can be selected as scored on an examinationexam. Using new or recently modified items as "Unscored" is a responsible practice when one is unsure of its characteristics. One can have a committee of 10 Subject Matter Experts review an item and miss that there are two possible correct answers. It isn't until the examination exam is administered to thousands that one learns of this.
Balance the Key
When a draft examination exam of multiple-choice questions items has been assembled, one should review the key location on each item to ensure that the distribution is relatively balanced. The number of items with the key in the "A" position does not have to match exactly the number of items with the key in the B, C or D position (on a four-option examination). However, it should be close.
