The ISD operates on a Four-Day School Week, with most school weeks running Tuesday through Friday. On Mondays, known as the Fifth Day, the ISD offers several enrichment opportunities and full-day childcare.
To maintain the same number of instructional hours as a traditional five-day week, there are some weeks during the school year when school is in session on Monday, and those dates are listed below.
Please read through the Monday offerings below to see if any of the programs are a good fit for your student. Please note each has different sign-up methods, locations, session times, etc.
