# Once Metrics ### Overview The scorecards and tables are defined in the pages below. ### Days/Week Days/Week is a key metric we track at Once. This metric tracks whether or not instructional sessions are occurring as scheduled. If sessions are not occurring, Once will not be effective, no matter how well trained and coached the instructor is. Therefore to improve school performance, the first thing we attempt to optimize is Days/Week. #### Definition Days/Week is the number of sessions that have occurred divided by the number of sessions scheduled, multiplied by five. The number of scheduled sessions is the number of dates in the instructor log that are one of the following: * Blank (we don't know what happened on that day) * Have a cycle entered (the student had a session and progressed in Once that day) * Have an "s" indicating a student absence * Have an "i" indicating an instructor absence * Have an "o" indicating that the instructor was unable to provide instruction because of another responsibility. Sessions are not scheduled during a school holiday or vacation. #### Days/Week Lost to Other Responsibility When schools are trying to improve their Days/Week ratio, they should first focus on those days when, even though the student and the instructor were both in school, they did not meet for their scheduled Once session. The typical reason this happens is that the instructor gets pulled from teaching Once during the day to cover other non-Once responsibilities within the school. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
