The Diagnostic Report includes a calculation titled Engaged Time for students who have mastered objectives. This shows you how much actual time students are likely spending working problems for Accelerated Math objectives. This is how Engaged Time is calculated:
(Number of objectives mastered x 50 minutes per objective) / (number of school days in the reporting period)
The number of school days in the reporting period is affected by days off that your administrator may have entered in the school calendar.
