ISEE Prep · Lower, Middle & Upper Level · ERB Official Assessment
The Stanine Score Most Families Misread. We Fix That First.
Independent School Entrance Exam / Section-by-Section Stanine Tracking
A Stanine 5 on the ISEE doesn’t mean your child is average. It means they outperformed the bottom half of private school applicants — a self-selected group of academically motivated students applying to competitive independent schools. Understanding this changes how you set goals, choose sections to target, and read every practice test report.
The Stanine Families Misread
The ISEE compares your child to other applicants to competitive schools — not the general population. Stanine 5 is the median of that selective group. Only 23% of test-takers ever reach Stanine 7 or above in any section. Most families open the score report expecting something like a school grade. What they find requires an entirely different lens.

Your Child's Stanine Is Harder to Earn Than It Looks
The ISEE is a peer-normed assessment. Every stanine your child receives reflects their performance relative to other students applying to the same competitive independent schools — not the general student population.
A student who earns straight A’s in school and feels well-prepared will often score a Stanine 5 on their first ISEE. That is the median — and it is genuinely difficult to achieve when the comparison group consists entirely of academically motivated private school applicants.

Competitive Threshold
A student who earns straight A’s in school and feels well-prepared will often score a Stanine 5 on their first ISEE. That is the median — and it is genuinely difficult to achieve when the comparison group consists entirely of academically motivated private school applicants.

Maximum Tests Per Year
The ISEE allows one test per testing season. Most families applying in fall only get two real attempts (Fall + Winter) before application deadlines. There is no “take it many times and pick the best” strategy. Each test is high-stakes.
0
Wrong Answer Penalty
The ISEE has no deduction for wrong answers. Every blank answer is a forfeited point with no compensating benefit. The optimal strategy is simple and absolute: always answer every question. This is the exact opposite of the SSAT.
1
The Stanine Confusion
Families compare stanines to school grades. A Stanine 5 reads as “average” — but it is the median of a highly selective test pool. Without context, prep goals are set against the wrong benchmark from day one.
2
The Retake Math
Maximum 3 tests per year, once per season. Most students only get two real chances. There is no high-volume retake strategy on the ISEE. Preparation quality — not quantity — is the only variable a family controls.
1
The Reasoning–Achievement Gap
The ISEE’s unique Stanine Analysis compares Verbal Reasoning to Reading Comprehension, and Quantitative Reasoning to Math Achievement. This gap reveals exactly what’s holding the stanine back — and most prep programs never surface it.
Prep Built Around Stanine Trajectories — Not Practice Counts
Every feature maps directly to a specific problem the ISEE creates. Section-level stanine tracking. Reasoning vs. Achievement gap analysis. Retake-aware progress planning. No generic test prep.

Section Stanine Tracking Across Every Test
HighScores tracks stanines for every section across every practice test. Watch Verbal Reasoning, Quantitative Reasoning, Reading Comprehension, and Mathematics Achievement move — or stall — test over test. Every session adds a new data point to the trajectory so you always know which section is improving and which requires more attention.

Reasoning vs. Achievement Gap Analysis
HighScores tracks stanines for every section across every practice test. Watch Verbal Reasoning, Quantitative Reasoning, Reading Comprehension, and Mathematics Achievement move — or stall — test over test. Every session adds a new data point to the trajectory so you always know which section is improving and which requires more attention.

Answer-Everything Practice Mode
The ISEE has no wrong-answer penalty. Leaving any question blank forfeits a potential point for zero benefit. HighScores’ ISEE practice mode trains the complete-everything habit until it is instinctive by test day — so no points are ever left blank out of uncertainty.
4
Retake-Aware Progress Planning
With only 3 possible tests per year, every practice session is calibrated against your child’s actual test calendar. HighScores flags when stanine improvement velocity needs to accelerate given the time remaining before the next official test window.
5
Sub-Skill Breakdown Within Each Section
Verbal Reasoning separates into Synonyms and Sentence Completions. Quantitative Reasoning separates into Word Problems and Quantitative Comparisons. Knowing which sub-type is holding the stanine back — not just which section — makes every prep session more targeted and efficient.
