My son has been attending Discovery World Montessori since he was 20 months old. The teachers there are great at what they do. Ms. Waffa was my son's first teacher. She was terrific at disciplining and getting him comfortable with his new surroundings. His kindergarten teacher, Ms. Cindy, taught him addition, subtraction, and writing composition. His elementary teacher, Ms. Marie, taught him multiplication and division WHEN HE WAS 1st GRADE! He was more advanced than his cousins, a second grader and third grader attending other private schools. Last year my son's 3rd grade SAT scores were way above his grade level. His Reading tested at the 5th grade equivalent. His Spelling, Writing, and Social Studies were tested at 8th grade equivalent. His Mathematics and Science were tested at 10th grade equivalent. My son is now in 4th grade. I can hardly wait what he will accomplish this year. The only thing I worry about is finding another school or teacher like Ms. Marie when he moves into sixth grade. Sadly, Discovery World Montessori doesn't offer classes beyond fifth grade. It's hard to find people especially teachers that care and are concerned about teaching the right stuff to develop young minds rather than just spewing out a curriculum.

This school is the best ever school we found since we moved from another state. We did visit all the schools in Diamond Bar/ Walnut prior to enrolling our two children. The director was very friendly and the administrator provided the guided tour. The way she described the child's growth with Montessori method was so easy to understand and we were sorry for loosing our first child's few years of sensitive period in another school.
One thing unique of this school is that all the staff members are happy and caring with great attitude. Another important thing was the school campus is well secured and they have two large playgrounds with large play equipment and a large canopy to protect children from sunburn. None of the other schools had all these in a package. Thanks to great school we found our second home for our children.
