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

The high school recently honored Class of 2016 alumna Erika Macrelli, a member of the school’s ecology-oriented Keep Islip Clean club, by dedicating a new bridge in the school courtyard to her memory. The June 7 ceremony featured a ribbon-cutting by Macrelli’s family and the release of more than a thousand ladybugs into the courtyard’s Insect Hotel.

“Within a day or two of learning about Erika’s passing last December, teachers, community members and 2016 alumni were already asking what could be done to recognize a student who brought a luminous spirit and beautiful smile with her whenever she walked into the high school,” said science teacher and KIC club adviser Wayne Mennecke. “The new bridge design was chosen with input from the Macrelli family for its sunrise pattern, which expresses hope, optimism and anticipation. It was assembled by KIC students and placed above the courtyard pond so that future classes of Islip students can continue to appreciate this spot the way Erika did as a member of KIC. The plaque affixed to the bridge is inscribed with Erika’s name and the phrase ‘Forever Loved,’ a perfect description for how Islip feels about Erika today and always. Islip always finds a way to work together as a community in support of a family in need. That level of kindness and generosity will extend into the next school year with future beautification projects in Erika’s name and by designating National Cancer Awareness Day on Nov. 7 as Erika Macrelli Day at Islip High School.”

“I did not have the pleasure of knowing Erika, but I can tell you that her spirit, her wonderful nature, is something that is a part of Islip,” said Principal Jon LaRochester. “We are fortunate that there are many people here that she was able to interact with. This is an exciting day because it is the first of what we hope to be many steps to continue to expand upon her dreams and create an environment that she would be proud of.”

“You are all leaders,” LaRochester told the seniors. “You all continue these wonderful traditions of achievement and rigor and excellence. Not only are you great students, you are great men and women. We congratulate you on your achievements.”
