School Notes

  • Immaculate Heart Central (IHC) is a Pre-Kindergarten to 12th grade Catholic school system and a ministry of the Sisters of Saint Joseph, who founded the school in 1881. IHC is the largest and most prominent non-public educational alternative in the Greater Watertown, NY area, educating over 450 students in grades Pre-K to 12. IHC Junior/Senior High School is fully accredited by the prestigious Commission on Secondary Education of the Middle States Association of Colleges and Schools. The High School enrolls over thirty international exchange students from eight to ten countries per year, bringing cultural diversity and universality that is an essential part of Catholicism. IHC`s highly respected St. John Bosco Pre-School program, educates three and four-year old students in a variety of two, three, and five-day per week programs. IHC`s student body is predominately from the Watertown Central School District, but includes students from about fourteen local school districts, depending on the year. Nearly thirty percent of IHC`s students are from families of active-duty soldiers stationed at nearby Fort Drum. IHC has a reputation for exceptional academics, with the highest average New York State standardized test scores among all districts in the local area (these tests include annual Math and English Language Arts tests for grades 3 to 8, and the New York State Regents Exams for grades 9 to 12). IHC Junior/Senior High School has a nearly 100% graduation and college matriculation rate. The Junior/Senior High School teaches a college-preparatory curriculum combined with the daily study and practice of the Catholic faith. The curriculum includes a number of Honors, Advanced Placement, and college EDGE courses in all core areas, a variety of electives, and musical, visual, and performing arts programs.IHC`s students are extremely active in community service projects throughout the local area. The Junior/Senior High School also has a highly respected athletic program which, despite the school`s relatively small size, has garnered numerous Section, League, and State Championship titles over the years.  IHC is truly a tight-knit "faith community" of students, parents, grandparents, teachers, thousands of alumni, local parishioners and other community members committed to quality Catholic education. The spirit of community, and the "small school feel," is one of the school system`s great strengths. IHC has a committed and quality faculty of teachers in Kindergarten through 12th grade, which enables the school to maintain class sizes of approximately 19:1.  High quality faculty combined with small class sizes promotes individual attention, participation, and the opportunity for group work. Come for a visit and see how good a school can be!

I attended one of the local catholic schools (St. Anthony's) until their merger into IHC Primary/Intermediate Schools. I began 4th grade at IHC Intermediate and graduated from IHC High school in 2013. I cannot even begin to express the sense of family, community, and love that I felt while attending. After growing up with my graduating class and spending so much time together through soccer, musicals, and the mystery players group I feel so truly blessed to have been a part of this school. I hope that once I achieve my degree in early childhood education that I can come back and give young students the same experience that I had.

We have children at Primary and Intermediate. We all love IHC! This is a school where the teachers and administration are caring, patient and go over and above the norm to accommodate the children's learning needs. Many Teachers offer tutoring after school for any child interested. The academics at IHC are outstanding. Parents are welcomed and are very involved school activities. My son loves playing lacrosse and basketball for his school. My daughter enjoys learning her Catholic faith and practices it daily. She loves partaking in the beautiful Christmas concerts every year. The children enjoy the class outings and special in school and after school activities provided to them by the school's Home and School Assoc in conjunction with parent volunteers. Most importantly, our children are learning in a faith based, respectful and nurturing atmosphere.

Best school in the area! We put two kids in IHC while they were still in elementary school - one has graduated and is doing great in college, and the other is thriving. We love the values, sense of community, caring teachers. The academics are excellent. For such a small school, the athletic programs are superb. Our daughter loves the art program.

My husband returned to college to pursue a Physician Assistant degree and he credits the great study habits that I.H.C. instilled in him with his success in the program.We knew that there was no other choice for our children but I.H.C. for the best education. Now our grandchildren attend the school and they are happy and thriving.We believe in I.H.C.. We see the sucess it produces and we love being part of the I.H.C. family.
