Testimonials

It does not go unnoticed that the teacher inspires an exchange of ideas in the classroom, which is a unique feature in a grade school class of this level. In fact the students appear to be excited about learning in the community created in this class in a way that I cannot compare to anything that I have experienced in my own educational career. Thank you for providing this class for the children. ---

ISSAC is one of the best charter schools in Orange County. My daughters love their teachers and friends at this school. Because of the smaller classroom sizes, they get more one-on-one interaction with their teachers. They do project based learning assemblies 6 times a year, which is great for all the students. In addition, they are learning Spanish and Mandarin. The Before/After School program is great as well for working parents. --- Lin A

Photo of the Day

Our kids have been at ISSAC for 5 years. We have seen them learn and grow their skills in math, science, and reading at a very fast pace. Having an on-site CTE lab helps tremendously, and teachers conducting science experiments during lunch breaks has been great! A lot of open space in the park next door for PE and after school sports clubs as well. ---Jad A

Issac Charter is an inclusive school with an excellent faculty. This is our daughter's first year and she is absolutely thriving in all areas. I highly recommend ISSAC to anyone looking for a better education for their child. ---
