Number of classroom hours offered to a representative student each week during the reporting period.
Number of classroom hours offered to a representative student each week during the reporting period.
Organizations should footnote all assumptions used.
This metric is intended to capture the number of instructional hours offered to students each week during the reporting period.
In an example of how this metric might be calculated, suppose a school begins the day at 8:00am and ends at 2:00pm. Each day approximately one hour is spent on lunch, breaks, or other non-classroom learning time. Therefore, each day, each student is offered five hours of instruction. Students attend school five days per week. The reporting organization would then report 5 × 5 = 25 hours.
This metric differs from Learning Hours (PI1836) in that this metric captures school time offered, while Learning Hours (PI1836) captures actual time provided. For example, if a calculation as above yields 25 hours for this metric, but within the reporting period school was cancelled for four hours in total because of snow or other bad weather, in that case would Learning Hours (PI1836) = (25 hours × number of weeks in the reporting period) - 4 hours.
