Cohort Graduation Rate What-If

What does it take to move our grad rate? Enter your cohort the official way and find out. You'll see your four-year rate, exactly how many students one point represents, and what happens when a handful more of them cross the stage. No PII. No login. Everything runs in your browser.

Build the cohort

No PII
First-time 9th graders

Students who entered 9th grade for the first time, four years ago.

Transferred in

Students who joined the cohort at any point during the four years.

Transferred out, verified

Only verified transfers to another diploma-granting program may be removed, not dropouts. That is the federal rule.

Graduated in 4 years

Students who earned a regular diploma within four years.

Each figure is one student.

Four-year cohort rate

79.0%

4 students in one point of grad rate

For context only: the most recent national four-year ACGR is about 87%. A school's rate depends on who it serves and how it counts, so we don't color-code yours. The number that matters is the one below.

The what-if

What if 5 more students graduated?

5more grads
+1.3points

That's the whole secret. Points are just students, counted one by one. Name the 5, build the plan, and the rate follows. Your counselors already know who they are.

Keep in mind

  • Event rates and cohort rates are different animals. An event rate counts one year's dropouts and always looks rosier. When someone quotes a graduation rate, ask which one.
  • Transfers out require documentation. Undocumented leavers stay in the denominator as non-graduates, which is why data hygiene IS grad-rate strategy.
  • The best predictor of this number four years early is freshman on-track status. Check any 9th grader in seconds with the Freshman On-Track Predictor.
How this works

This tool computes the Adjusted Cohort Graduation Rate (ACGR), the official federal measure. In words: take everyone who entered 9th grade for the first time four years ago, add students who transferred in, and subtract students who verifiably left for another diploma-granting program. That is the adjusted cohort. Divide the number who earned a regular diploma within four years by that cohort, and you have your rate.

Who may be removed from a cohort is strict on purpose. A student comes out of the denominator only with documentation that they enrolled in another school or program that grants a regular diploma, emigrated, or died. Dropouts, students who leave for GED programs, and students who vanish without paperwork all stay in the cohort and count as non-graduates. That is why chasing down enrollment records is not clerical work. It is graduation-rate work.

One more trap: the event rate. An event dropout rate counts the share of enrolled students who drop out in a single year, so it is always a much smaller, friendlier-looking number than the share of a cohort that never finishes. The two get confused constantly, sometimes by accident. When a rate gets quoted, ask which kind it is.

A graduation rate is a mirror, not a motor. It moves when specific students get specific support in time.
