Evaluation Centers

The people and organizations listed below offer educational testing for admission purposes. The Langley School does not endorse a particular center or individual. These names are provided to assist you in arranging testing for your child. Each individual or organization sets its own fees. Note: If you need names of testers who are available during this time of social distancing and shelter-in-place, please let us know and we can help find one.

  • Applicants to junior kindergarten, kindergarten, and grade 1 who are 5 years old and younger should take the Wechsler Preschool and Primary Scale of Intelligence (WPPSI-V).
  • Applicants to grades 1 through 5 who are 6 years old and older should take the Wechsler Intelligence Scale for Children (WISC-V).
  • Applicants to grades 6 through 8 should take the SSAT test. Students must pre-register with SSAT (www.ssat.org) and know that Langley’s school code is 4507. Note: As of April 2020, SSATs are currently not available due to COVID-19, so we are accepting WISC testing as a substitute.
