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

Islip HS Alumna Is Shooting for the “Starz”

Chrystle Stewart, an alumna of Islip High School’s Class of 2019 and current sophomore at Five Towns College, can boast a soaring acting career. She recently won a a role on the upcoming Starz television series “Run the World” and has filmed several national commercial campaigns.

After being hired for “Run the World,” she reached out to several of her Islip educators to let them know and thank them for their support, guidance and encouragement throughout her educational career, including video production teacher Mike Reilly.

“Video production will forever be my favorite class at Islip High School, and it gave me the opportunity to express myself creatively,” Stewart said. “With the help of Mr. Reilly, it provided a space to collaborate with my peers to create films and showcase myself on camera through acting, which is a passion of mine. I’m so grateful to have had a teacher who pushed me and his students to become the best we could be, and I have been blessed to book two major projects in the film industry, which is only the beginning.”

“Chrystle is one of those individuals that lights up a room when she enters,” Reilly said. “When she called to tell me about the amazing news, to be honest, the only shock I experienced was how short of a time it had taken for Chrystle to be noticed, recognized and hired. It was not about if she was going to succeed, but a matter of when. For this to happen so quickly is a testament to Chrystle’s work ethic, desire and dedication. Collaborating with her classmates in high school, her group won a few local and national competitions. This time, the reward is a paying job and a chance for everyone to truly see what a talent Chrystle is.”

Tyler Cirulnick Named All-Eastern Musician

High school senior Tyler Cirulnick was recently selected for the National Association for Music Education’s All-Eastern Mixed Choir. This selection places Cirulnick among the most accomplished student-musicians in New York and one of only seven chosen from the state in the All-Eastern Mixed Choir’s Alto II section.

“I have witnessed countless examples of quality performers, and Tyler has the skill set to succeed in this field,” said her teacher, Dr. Rich Harris. “I believe her successes over the past few years in chorus and theater have helped define her as a willing and passionate artist who understands what it takes to succeed in the arts. She performs with such a high level of passion and is never done working and reflecting on her performances. Tyler notices the small things that matter in this art, but more importantly, she questions why they matter. I am beyond excited for Tyler, as she is recognized as one of the best vocalists on the East Coast.”

“We wish to honor and congratulate both Tyler and Dr. Harris for this stellar achievement,” said Brian Kroll, Islip’s director of fine and performing arts.
