A Message from the Principal:
Islip High School Community,
As we open the doors of the high school for the start of the 2021-2022 school year, we do so with great pride and excitement as we welcome all of our students back. Our faculty, staff, and administration have worked diligently since the end of last school year to ensure that this year will be a full, exciting, healthy, and safe year for all members of the Islip High School Community.
This school year also carries with it a very special label and welcomes a very special group of young men and women to the high school. The 2021-2022 school year will mark the 100-year anniversary for Islip High School. When construction was completed, the first high school opened its doors in the fall of 1921, under the motto, "Enter to Learn... Go Forth to Serve," a motto that has become the foundation for so much of what we try to provide our students. As the start of the 100th school year begins, we also welcome the Class of 2025. This special group of students also carries a label, as they will be the 100th graduation class in Islip High School's storied history.
Join me as we set our attention to the wonderful opportunities that we create for our students this year, to a safe and healthy return to normal, and to our "Re-Connecting & Re-Engaging with Kindness, Caring, and Innovation."
Let's have a great school year, Islip!
Jon LaRochester - Principal
