Our Results

cogat chart

This chart shows a correlation between the number of years enrolled at HWIS and cognitive development. Note that 63% of students at HWIS for four years or longer tested as gifted—100% were either gifted or above average—while 7% of students enrolled after 1 year were assessed as gifted. This supports the research showing that students gain enhanced cognitive abilities as a result of being enrolled in immersion programs.

Even though they receive instruction in English for only 20% of the day in Kindergarten and 1st grade, when assessed by standardized testing in English, HWIS students outperform students of Gifted & Talented public schools and independent schools nationwide.


Avant 4se
This chart shows the proficiency level achieved by our grade 4 students in the Mandarin program, across both campuses, as compared to the national norm for Mandarin immersion students in the U.S. in grades 4 and 6. The Avant 4se is specifically designed for immersion students, and assesses listening, speaking, reading, and writing skill levels.

Supera is one of the TerraNova series of standardized tests used in the U.S. to assess K-12 student achievement in reading, language arts, mathematics, science, social studies, vocabulary, spelling, and others. This chart shows the proficiency level achieved in Language Arts Literacy and Mathematics by our students in the Spanish program, weighted against the national norm for grade equivalency: late grade 3 students (3.8) perform at an early grade 5 level (5.1) for Language Arts Literacy, and at an early grade 6 level (6.2) for mathematics, while late grade 4 students (4.8) perform at a mid-grade 6 level in both Language Arts Literacy (6.6) and Mathematics (6.4).
