A Message from the Principal:
Islip High School Community,
We have finally completed the development and review of the Spring Semester Cohort Calendar beginning on Monday, January 4, 2021, which you will find linked in the sidebar of this page. This calendar reflects the complete schedule for the Gold and Purple Cohorts while identifying the Day 1/Day 2 Schedule. The calendar also reflects holidays, scheduled snow days, and our June testing period, which is still to be determined. As decisions regarding NYS Regents Examinations are made by the NYS Education Department, we will update our June testing to reflect these changes.
Thank you and please feel free to call my office or the IHS Guidance Department at the numbers listed above if you have any questions.
Jon LaRochester - Principal
