A good graduation rate depends on the type of school you’re evaluating. For four-year colleges, anything above 70 percent is generally considered strong, while rates above 80 percent signal a school where most students finish their degrees. For high schools, the national average sits around 87 percent, so schools hitting 90 percent or higher are performing well. These numbers shift significantly based on the type of institution, the students it serves, and how “graduation rate” is actually measured.
How Graduation Rates Are Measured
Before you can judge whether a rate is good, you need to understand what the number actually tracks. For four-year colleges, the standard metric is the six-year graduation rate. That means it counts how many first-time, full-time students earn a bachelor’s degree within six years of starting, which is 150 percent of the “normal” four-year timeline. This is the figure colleges are required to report to the federal government through the IPEDS database.
The six-year window exists because many students change majors, take lighter course loads, or need extra semesters to finish. A school reporting a 65 percent graduation rate isn’t saying 35 percent of students dropped out yesterday. Some of those students transferred to another school and graduated there, some are still enrolled, and some did leave without finishing. The standard metric doesn’t capture transfers, which means schools with high transfer-out rates can look worse than they actually are.
For two-year community colleges, the equivalent metric uses a three-year window (150 percent of the normal two years). High schools use a four-year adjusted cohort graduation rate, tracking how many students in a freshman class earn a diploma within four years.
Benchmarks for Four-Year Colleges
The national six-year graduation rate is 63 percent at public four-year institutions and 68 percent at private nonprofit four-year institutions. Those averages give you a baseline, but the range across individual schools is enormous. Highly selective universities routinely post rates above 90 percent, while open-admission public universities may graduate fewer than 40 percent of their students in six years.
Here’s a rough framework for evaluating a four-year school’s graduation rate:
- Above 80 percent: Excellent. This is typical of selective private colleges and flagship state universities. Students at these schools have strong academic preparation, financial resources, and institutional support systems.
- 60 to 80 percent: Solid. Most four-year public universities fall in this range. A rate in the upper end of this band is competitive, while the lower end is close to the national average.
- 40 to 60 percent: Below average. Schools in this range may serve a large share of part-time, working, or financially constrained students. The rate alone doesn’t mean the school is failing, but it’s worth investigating why students aren’t finishing.
- Below 40 percent: A red flag worth examining closely. Some schools in this range are doing meaningful work with underserved populations, but the low completion rate means most enrollees won’t leave with a degree.
Why Selectivity Skews the Numbers
A school’s graduation rate reflects its student body almost as much as its quality. Elite universities admit students with high GPAs, strong test scores, and families that can cover tuition. Those students were already likely to graduate no matter where they enrolled. A regional public university that admits nearly everyone, including students who work full time or are the first in their family to attend college, will always post a lower rate.
This is visible in the data on Pell Grant recipients, students from lower-income families who receive federal need-based aid. Pell recipients graduate four-year institutions at a rate of about 53 percent, compared to 73 percent for non-Pell students. That gap narrows dramatically at top research universities, where Pell students graduate at roughly 87 percent compared to 91 percent for their peers. The institution’s resources and support infrastructure make a measurable difference, but so does the financial stability students bring with them.
When comparing schools, try to compare within similar categories. A public university graduating 55 percent of its Pell-heavy student body may be doing more impressive work than a private college graduating 85 percent of students who arrived with every advantage.
Community College Graduation Rates
The three-year graduation rate at two-year institutions is about 34 percent nationally. That number looks alarming in isolation, but community colleges operate differently from four-year schools. Many students enroll with the intention of transferring to a university after a year or two, and those successful transfers aren’t captured in the graduation rate. Others attend part time while working, stretching their timeline well beyond three years.
A community college posting a graduation rate above 40 percent is performing above average. Rates above 50 percent are strong. But when evaluating a community college, transfer rates and combined completion metrics (which count students who either graduated or transferred) give you a much fuller picture than the graduation rate alone.
High School Graduation Rates
The national average high school graduation rate was 87 percent for the 2021-22 school year, up seven percentage points from a decade earlier. For high schools, the bar for “good” is higher than for colleges because the expectation is that nearly all students should finish.
A high school graduation rate above 90 percent is solid. Rates above 95 percent are common in well-resourced suburban districts. Schools falling below 80 percent are typically flagged for additional scrutiny and intervention by state education agencies. When evaluating a high school, look at subgroup data as well. A school with a 92 percent overall rate but a 70 percent rate for certain student populations may have equity gaps that the headline number masks.
How to Use Graduation Rates When Choosing a School
Graduation rate is one of the most useful data points when evaluating a college, but it works best alongside other information. A high graduation rate paired with high student debt might mean students are finishing but paying a steep price. A moderate graduation rate at a school with generous financial aid and strong career placement might actually deliver better outcomes.
When you’re comparing schools, pull graduation rates from the College Scorecard (collegescorecard.ed.gov), which uses federal data and also shows rates broken down by income level. Look for schools where the gap between lower-income and higher-income students is small, because that’s a sign the institution is investing in student success rather than just admitting students who would have graduated anywhere. A “good” graduation rate ultimately means one that’s strong relative to the students the school actually serves.
