IQ Testing

An IQ test measures verbal and non-verbal problem solving abilities. It is not an achievement test. To be considered for admission to Open Window School, applicants must achieve a full scale or composite score at the 95th percentile or above. This score is an indicator of a child’s potential for success at Open Window. Because the IQ test is cognitive, rather than an achievement test, children should not be prepped for the test. Some helpful advice about what to tell your child about an IQ test can be found here. If your child does not score at or above the 95th percentile on the WPPSI-IV, please contact our office. We are happy to discuss whether Open Window is the best match for your child. Although it can be administered to younger children, we recommend waiting until your child is 4 ½. Test results are valid for two years. 

For students 6 years of age and younger we accept either the Wechsler Preschool and Primary Scale of Intelligence (WPPSI-IV) or the Stanford-Binet, V. For students older than 6 years of age we accept the Wechsler Intelligence Scale for Children (WISC-IV or WISC-V). If your student attends a full-time public school gifted program, we are willing to accept the test results that qualified him/her for that program. 

Families must have IQ testing done privately, by a licensed psychologist – examiner’s schedules can fill quickly, so we recommend scheduling your child’s testing as early as possible. If the financial burden of an IQ test is a hardship on your family, please contact our Director of Admission, Calley Hart

Open Window requires all applicants to submit an IQ test with a full scale score in the 95th percentile or above. A composite score may also be considered. Students applying to third grade or above must also submit achievement testing.

Achievement Testing

Students applying to third grade or higher must also submit achievement testing. This can be standardized group testing from a current or previous school (ITBS, etc) or can be administered privately.

For applicants to fifth through eighth grade, we require either the Independent School Entrance Exam or the Secondary School Admission Test. Families should register for the ISEE or SSAT online, and include Open Window School to receive the results of the test. Our ISEE code is 481722 and our SSAT code is 5543.
