A Message from the Principal:

Welcome to the 2018-2019 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. In the last few years, we have launched a Career Academy Program at Islip High School. The Islip Academy Program is comprised of the S.T.E.M., Business, and Media and Public Affairs Academies. These programs will allow students with an interest in any of these three 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 three in 2014-2015 to 19 in 2018-2019. Islip students can now take courses accredited by Suffolk County Community College, SUNY Farmingdale, St. John’s University, Long Island University – CW Post, and Hofstra University. Last June, we were proud to graduate our very first cohort of AP Capstone students. 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 the Twitter site, 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. You can also find IslipHS on Snapchat! 

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 Wednesday, September 5th. 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.

High Schoolers Make a Difference Donating Jeans

High Schoolers Make a Difference Donating Jeans
High school students and the Junior Chamber of Commerce Club worked on the Teens for Jeans campaign again this year, with students, staff and community partners recently collecting more than 500 pairs of gently used or new denim jeans to be donated to teens residing in homeless shelters. Students in teacher Renée Clock’s work experience class then interned at the Town of Islip Youth Bureau, sorting and packaging the jeans for delivery.

Community partners on this initiative also included Town Councilwoman Mary Kate Mullen; Suffolk County Legislators Tom Cilmi, Steven J. Flotteron and William J. Lindsay III; Kennedy LI Realty; and the Exchange Ambulance of the Islips

“We began participating in the Teens for Jeans campaign seven years ago through,” said Clock. “We originally partnered with Melanie Holz of the South Shore Community Organization. This year, we had seven drop-off sites within the Town of Islip. Youth Bureau Director Tim Mare has been indispensable in helping us coordinate this campaign and the pickup and delivery of the jeans to the local homeless shelters and outreach centers in our area.” 

Cilmi, whose office has participated as a drop-off site since 2012, told the students, “Keep helping others in your community and be proud of yourselves for taking the time to help the less fortunate.”

As the students were loading the jeans on the truck, Clock reminded them how important it is to help others and to seek opportunities to be leaders.  
“You do not need to spend money to help others,” said Clock. “Find a way you can help and make a difference in someone’s life, it will keep you humble. Remember, there will always be people who need your help and there will always be a way for you to help others.”

High Schoolers Serve as Mentors at Buccaneer U

High Schoolers Serve as Mentors at Buccaneer U

In the high school’s Buccaneer University eighth-to-ninth grade transition program, created by Assistant Principal Lisa Ward and school counselor Nicole Hall, high school students are recommended by teachers to participate in being mentors to incoming ninth graders throughout the latter’s freshman year.

Once BU mentors are selected, they are assigned to a group of eighth graders at the middle school; these mentors will remain with the same groups of students throughout the transition process so that the younger students recognize a familiar face at the high school. In the first of four meetings, BU mentors visit the eighth grade to introduce themselves and answer any questions they have about the high school. Next, the eighth graders visit the high school and participate in eighth grade rounds, led by the mentors, who then visit the eighth grade again to answer any follow-up questions. In the last visit, which takes place the week before school starts, BU mentors lead their groups in icebreaker activities and classroom presentations providing information on the start of school.
