Proficiency Certification is a workflow designed to give school and district administrators an organized approach to creating high-stakes proficiency data from a collection of inputs across multiple classrooms and school years. It's best thought of as a way to periodically identify complex situations (such as a standard being scored by multiple teachers) and validate the result for the purposes of graduation requirements or transcripts. It also provides tools to override proficiency scores, add data from external sources such as summer school, and modify historical proficiency scores.
Only certified proficiency scores (for which this process has been completed) will be shown on proficiency transcripts, though ongoing (real-time) proficiency data is available in many other reports in the system. Certification can be completed as often as necessary by any user with sufficient permissions, but it is best thought of as something to complete at the end of each year or term.
