Which test does my child’s school require?
It varies by school and grade. Most Houston private schools accept the ISEE; many Catholic schools use the HSPT; a few accept the SSAT. Check each school’s admissions page — or start your Roadmap and we’ll map it out for you.
What test do younger applicants take?
For Pre-K and kindergarten, schools typically use a brief readiness or cognitive screening (often the OLSAT) rather than a full entrance exam.
Can one test be used for several schools?
Often yes — a single ISEE score can be sent to multiple schools. The ISEE can be taken once per testing season.
