Strategic StudentGap Finder
Enter a rate for each student group. Gap Finder sorts the groups, compares each to the all-student average, and flags the biggest gaps so you know where to focus support. No PII. No login. Everything runs in your browser.
Subgroup rates
Prefilled with sample data you can editFor graduation and proficiency, higher is better. The tool flips its logic automatically. For a custom metric, tell it which direction is the concern.
Where the gaps are

The gap is the distance, in percentage points, between the highest and lowest group rates shown. The average is weighted across the groups you entered, so a group of 5,800 students pulls it harder than a group of 140. Because a student can belong to more than one group, that average is across group memberships, not a headcount of unique students.
For chronic absence, the label on each group uses the school-level scale from Attendance Works: Low under 5%, Modest 5 to 9.9%, Significant 10 to 19.9%, High 20 to 29.9%, Extreme 30% and up. Those are descriptions of a group rate, not a label on any student. Every other metric is read relative to the weighted average (above or below), with the concern side marked, because fixed cut points for suspension, course failure, graduation, and proficiency vary by state and we would rather not invent them.
Groups under 10 students are listed by name without a rate. A rate on a handful of students swings too far to compare, and most states suppress at that size for privacy (see NCES, Best Practices for Determining Subgroup Size).
A gap describes what the system produced for a group, not a cause and not a verdict on the students in it. The next step is a question: what is different about the experience of the group that sits furthest from the average, and what can we change about it?
A gap shows where to look, not where students fall short. Use it to ask sharper questions and direct support, alongside what you already know about your students.
