A Message from the Principal:

Welcome to the 2016-2017 school year.  This is a year of new beginnings and exciting new programs and course offerings.

At Islip High School we have a steadfast belief that it is our responsibility to educate the whole child in preparation for not only college and career, but for life in general.  Students in the 21st century need to be prepared to make contributions in their local communities and in the global community as well.  To accomplish this, our students need to be prepared with skill sets that include creativity, communication, collaboration, critical thinking, problem solving, technological proficiency, and global awareness.

To further address these important skills, we have implemented a number of new courses and programs.  Last year, we launched our first Academy Program at Islip High School.  The Islip Academy Program is comprised of the S.T.E.M. and Business Academies.  These programs will allow students with an interest in either of these two fields to take coursework and have experiences that will better prepare them for their post-secondary studies. 

We have also increased our partnerships with local colleges and universities to provide our students with more opportunities to earn college credit while still enrolled in Islip High School.  We have increased our duel-credit course offerings from 3 in 2014-2015 to 13 in 2015-2016.  Islip students can now take courses accredited by Suffolk County Community College, SUNY Farmingdale and St. John’s University.  
2016-2017 will also mark the beginning of a new Advanced Placement course.  AP Capstone is an innovative diploma program that provides students with an opportunity to engage in rigorous scholarly practice of the core academic skills necessary for successful college completion.

AP Capstone is built on the foundation of two courses — AP Seminar and AP Research — and is designed to complement and enhance the in-depth, discipline-specific study provided through AP courses. It cultivates curious, independent, and collaborative scholars and prepares them to make logical, evidence-based decisions.

Our goal at Islip High School is to give our students as many opportunities as possible to explore and learn about a variety of careers.  We have also added exciting new courses/programs such as Cosmetology (Career and Technical), Video/Radio Production (Music) and Virtual Enterprise International (Business). Each of these courses will take place in classrooms that have been redesigned and equipped to give the students a “real world” work experience. 

In an effort to increase communication with parents/guardians and students on the happenings at Islip High School (IslipHS), I encourage you to sign up to use Twitter ( Twitter is a website that allows for quick and consistent, two-way communication.  I have created an account to disseminate useful information about IslipHS and valuable parent resources instantaneously.   Signing up is easy. Go to, create a user profile, and once you are registered, search for our school username (IslipHS). Then click on the profile and select “follow”. We are on Facebook and Instagram as well.  To join our Facebook page simply visit and become a fan of our page.  You can also follow IslipHS on Instagram to view pictures of our exciting school events. 

Despite all of the new digital communication put in place for your convenience, there is no substitute for live communication with members of our Islip High School staff.  Please work directly with our Assistant Principals on all issues regarding your children.  Ms. Ward, Assistant Principal for grades 9 and 10, can be reached at 650-8315, and Mr. Juengerkes, Assistant Principal for grades 11 and 12, can be reached at 650-8320.

The first day of school for students is Tuesday, September 6th.  First period begins at 7:20 a.m.  Students are to report directly to their first period class as indicated on their schedule.  Any questions regarding schedules should be directed to the guidance department. 

Please remember, most important to student success is parent involvement.  Please continue to ask questions and keep the lines of communication open.  Feel comfortable emailing me at or calling me at 650-8305 with any concerns or questions you may have. As a parent myself, I understand the importance of feeling confident that your child is in a positive and nurturing learning environment.

I look forward to working with you this year.   My door is always open.  Please feel free to contact me at any time.

Michael Mosca, Principal
Islip High School
