Graduation Rate
The four-year adjusted cohort graduation rate of a school district, the share of first-time ninth-graders who earn a regular diploma within four years.
The four-year adjusted cohort graduation rate (ACGR) of a school district. NCES defines it as "the percentage of first-time ninth-graders in public high schools who graduate with a regular diploma within 4 years" (NCES).
The cohort is adjusted rather than fixed. NCES describes the adjusted cohort as "the number of first-time 9th-graders plus students who subsequently transfer in minus students who subsequently transfer out, emigrate, or die during 9th, 10th, 11th, or 12th grade". Students who move away are therefore removed from the denominator rather than counted as non-graduates, and students who arrive are added.
"Regular diploma" excludes certificates of attendance, alternative credentials and equivalency awards, so a district that graduates many students on non-standard credentials records them outside this rate. The Department's collection specification for the measure is published as EDFacts file specification 150.

Four-year graduation rate
levelThe district's most recent reported four-year adjusted cohort graduation rate, from school year 2020-21. No trend accompanies it: the collection loaded here holds a single school year, so there is no earlier point to compare against.
Considerations#
The measure is far less precisely published than its reputation suggests. Of the 11,673 districts in this release, fewer than a third report an exact percentage. Most report either a range or a bound of the form "greater than or equal to 80 percent", because the Department, where "a population or subgroup represents too few students", releases "a range of values rather than an actual, precise value" (ED Data Express FAQs). Since graduating cohorts are small in most districts, this affects the majority of them. The single figure Birdseye shows for those districts is our own estimate lying inside the published range, and small differences between two districts often sit inside that uncertainty rather than describing anything real.
Only districts operating high schools have a graduating cohort, so about 11,700 districts report here against roughly 17,000 reporting assessment results. A tract whose district has no high school shows nothing.
School year 2020-21 was disrupted by the pandemic, and states varied in how they handled credit, attendance and graduation requirements that year.
The rate is self-reported by states to the Department, which reviews the submissions but leaves states to certify them.
This is a district-level figure displayed on a census tract. It describes the district covering that tract, not the tract, and not any individual high school within the district. It covers public schools only.
