A free spreadsheet to demonstrate how job analysis results can be transformed into recommended test blueprints.
The development of credentialing exams (certification, licensure, etc.) requires strong psychometric practices and validity documentation, as outlined by standards such as NCCA and ANSI. One of the first big questions is “How do we decide what the test should cover?” There are 3 steps to answering that question.
This spreadsheet provides a simple example of Step 3, which you can adapt to your needs. Simply fill out the form to download.

A job analysis will produce a list of tasks, sorted into domains, and rated by job incumbents on aspects such as frequency and importance. We need a way to convert this into a test blueprint, namely what percent of the test should cover each domain. Domains that have more tasks deserve more weight. Domains that have higher-rated tasks also deserve more weight. This spreadsheet provides a simple way to accomplish this process.
More advanced methodologies will also map tasks to knowledge statements, evaluate subdomains, and introduce other levels of complexity. This is extremely important in many cases, but for many exams the process here will suffice.
