There are many factors to consider when implementing a certification exam program. The benefits of a well-developed and implemented program are many, ranging from well-prepared employees to increased profits due to a knowledgeable team. The tests themselves are most often a revenue generating process as many different populations can seek to be certified. But getting there requires multiple steps to ensure a quality exam.
It is critical to ensure that each step in the development process is well planned and executed. Below is an overview of steps that need to be taken to ensure a quality outcome. There are other steps that are followed by different development programs. However these are the major steps and processes.
- Begin by identifying the end results needed. What do the people who receive the certification need to be able to do.
- Once the end results have been identified, the steps needed to produce the end results have to be documented. For example, if the test covers driving different types of vehicles (perhaps cars, trucks, motorcycles, golf carts or others) include all the steps needed to drive each type of vehicle. This is known as a task analysis.
- Next a blueprint is developed. A team of experts most often develops the blueprint. The experts who develop the blueprint generally include practitioners and others who have expertise in the area. The blueprint describes each component of the task analysis. The blueprint identifies each area that will be tested by the exam. Most blueprints include the number of items for each objective that will be included on an exam. They also usually assign a weight to each topic area. Multiple examples of templates are available on line. Here is just one example.
- Once the blueprint is developed it needs to be validated by other subject matter experts (SMEs). Note that it is not expected that one person will have expertise in all areas covered by a full exam.
- At this point the item writing process begins. The very first step is to agree on the blueprint. Most often there are changes. Additions and some deletions can also happen, as topics may not be appropriate for the specific exam, may be covered on another exam, or might make the exam too long. Also there may be changes to the percentages and other edits before the team agrees on who will develop which items and the number of items each person will write.
- Handouts for the types of items to be included on the exam (for example multiple-choice, matching), how to write items, and what should and should not be included in an item are generally passed out and reviewed before participants begin writing the items. There are often handouts to explain how to input questions into the item development program used for item input.

- It is important to let item writers develop just a few items (about three) and stop so that their items can be reviewed for feedback. Generally letting them write for no more than 30 minutes works well. It is also a good idea to review with the full team so that everyone hears the feedback. For a large group, the exam facilitator may want to just review one item written by each developer. Have them post their items in a way that allows for only the facilitator to see them. The exam facilitator should choose items to review so that different areas that need attention can be discussed.
- Once the first review is completed it is time to let the writers write more items. The exam facilitator needs to continue to review the developers’ items so that if they are making errors the facilitator can let them know what needs to be fixed. Usually a recommended rewrite helps. If the facilitator doesn’t know the subject area, they can use a gibberish word that will allow for the needed concept to be explained.
- After a period of time (usually two hours works) take a break and then begin to review the items. The facilitator can provide feedback on test development techniques and the developers need to provide feedback on the content of the questions. If there is agreement that the question is good, then it can be approved. If there isn’t agreement, the team can try to repair it. But in some cases it is better to delete the question, as time is often a factor in getting the number of questions that are needed and approved completed in the allotted timeframe.
Once the development workshop is completed the questions are sent out for review. Each question needs to be reviewed by multiple reviewers. Also each reviewer should only review a limited number of items to ensure the confidentiality of the exam.
