As a former student of 5 years and employee of 8 years, I can say with confidence that joining Newton Kumon was one of the best decisions I've ever made.
As a Newton Kumon student, I enrolled in the Math and Reading programs, progressing from level D to I in Math and level DI to K in Reading. I attribute much of my academic success to the Kumon program, and particularly to the investment of the instructors at this center, Winston and Jane. It is evident that they genuinely care about the students' success, and they are constantly customizing worksheet combinations to fit the needs of each particular child.
I got a 2330 on my SATs - a perfect 800 on my math section, and without a doubt, I could not have accomplished such a feat without the strong foundations of mathematics that Kumon and Winston/Jane had taught me. Reading taught me critical reading and analytical writing skills that allowed me to excel on the reading and writing sections of the SATs as well.
By no means is this center solely dedicated to building a foundation for standardized testing - I went from a student who could barely make it into the 5th grade honors level math to a student who was consistently in honors math courses in high school, getting straight A's, and got a perfect 5 on my AP Statistics exam. I also differentiated myself as a critical thinker in my literature classes in high school, receiving numerous awards for excellence in those English courses and A's as grades.
Overall, Newton Kumon is a great learning environment for both students and parents. Parents are able to keep track of what their kids are learning and succeeding in, and students are able to reap the rewards of their work at the Kumon center, at home, and in school.
I've spoken to friends who have went to other centers before, and many of them recount stories of apathetic instructors and lack of academic improvement. Often, I refer them to the Newton center, and they find that the instructor(s) truly do make all the difference.
