Admissions Tests and Assessments: Which One Your Child Needs
Based on The Firat Guide, the Houston area private school admissions book authored and updated by Ibrahim Firat since 2014.
The test your child takes depends on the grade they are entering. Young children applying to Pre-K, kindergarten, and the early grades usually take an individually administered readiness or cognitive assessment such as the WPPSI. Applicants to the middle and upper grades most often take the ISEE, the entrance test most Houston private schools use, including the major Catholic college-preparatory high schools. A few schools accept the SSAT. Firat prepares Houston students for the ISEE and helps families arrange the assessments younger applicants need.
Match the test to your child's stage
Different entry points call for different tests. Here is what Houston schools typically use, by stage.
| Stage (entry) | Common tests | What it is |
|---|---|---|
| Early childhood Pre-K & kindergarten | WPPSI-IV, OLSAT, readiness screenings | A short, often one-on-one readiness or cognitive check, sometimes play-based. |
| Lower / elementary grades 1–5 | WISC-V, WPPSI-IV, OLSAT, ISEE Primary/Lower | An individually administered cognitive test, or the first ISEE levels. |
| Middle school grades 6–8 | ISEE (SSAT at a few) | Standardized entrance exams taken independently by the student. |
| High school grades 9–12 | ISEE Upper (SSAT at a few) | In Houston the ISEE is standard, including at the major Catholic college-preparatory high schools. |
Early childhood and lower school: readiness and cognitive testing
For the youngest applicants, many Houston schools use an individually administered cognitive assessment rather than a group entrance exam. The most common is the WPPSI-IV (Wechsler Preschool and Primary Scale of Intelligence, ages 2 years 6 months to 7 years 7 months). Slightly older children may take the WISC-V (ages 6 to 16). Some schools instead use a group school-ability test like the OLSAT or a developmental readiness screening. These are not tests you cram for; they measure reasoning and readiness. What helps is a calm, well-prepared child and a proctor who knows how to put them at ease.
Firat can help with the early tests too. Through our Firat Assessment and Roadmap, we help families understand where a young child stands and prepare for these screenings, so the results reflect your child on a good day. Start your Firat Assessment and Roadmap →
The ISEE: the test most Houston families need
For most private school applicants from upper-elementary through high school, the ISEE (Independent School Entrance Examination) is the test that matters. It comes in four levels, Primary (entering grades 2–4), Lower (5–6), Middle (7–8), and Upper (9–12), and is scored on a 1 to 9 stanine that shows how your child compares to other applicants. In Houston it is the standard exam at the leading independent schools and at the major Catholic college-preparatory high schools alike, so most families only need to prepare for one test even when applying to several schools. For a school-by-school view, see Which Houston Schools Require the ISEE.
Firat Education is Houston's ISEE prep specialist. We have prepared Houston students for the ISEE since 2008, with individualized tutoring in all four sections, full-length diagnostic practice tests, and strategy built around your child's target schools and timeline. Explore ISEE test prep →

What about the SSAT and HSPT?
In Houston, the ISEE is the standard entrance exam, used by both the leading independent schools and the major Catholic college-preparatory high schools, including Strake Jesuit, St. Agnes, St. Thomas, and St. Pius X. The SSAT (Secondary School Admission Test) is accepted at a few schools but is far less common locally, and it appears more often at boarding and out-of-area independent schools. The HSPT (High School Placement Test) is used by Catholic schools in some other regions, but it is not the norm in Houston. Because requirements vary by school and grade, confirm each school's current test before you register.
Frequently asked
Which test does my child's school require?
Most Houston private schools use the ISEE, including the major Catholic college-preparatory high schools; the SSAT is accepted at a few; and early-grade programs use the WPPSI or a readiness screening. Confirm each school, see Which Houston Schools Require the ISEE, or start your Firat Assessment and Roadmap and we will map it out.
What is the WPPSI?
An individually administered cognitive assessment (ages 2:6 to 7:7) that many schools use for Pre-K through early-elementary admissions. The WISC-V is its counterpart for ages 6 to 16.
What do the youngest applicants take?
Usually a brief readiness or cognitive screening (often the WPPSI or OLSAT) rather than a full entrance exam.
Can one test be used for several schools?
Often yes. Because so many Houston schools use the ISEE, a single ISEE score can be sent to multiple schools, and most families prepare for just one exam.
How early should we start ISEE prep?
Most students begin 3 to 6 months before the test date; applicants to the most competitive schools often start earlier. See When to start.
