Why This Indicator Matters

Students who graduate from high school have higher wages, lower unemployment and are less likely to need public assistance than those who do not graduate. Their long-term physical and mental health is also better if they graduate from high school.

What the data shows
For the 3 year period of this series, the data has been relatively stable. At a state level, 86.5% ,87.5% 87.1% graduated for the years 204,15 and 2016. In the latest year, the counties with the highest graduation rates were: Cumberland County at 87.7% and Aroostook at 86.7%.
The lowest rates were at Piscataquis County at 72.8% and Sagadahoc County at 73.9%.
Nationally, the graduation rate for 2015-2016 school year (called 2016) is 84.1%, so Maine is better than average, and is ranked 18th. The State is working toward a goal of having a 90 percent graduation rate.

Footnotes: In this series, the calculation is at the student level rather than the school level.  This makes it "weighted". For example, suppose a county had 3 schools, one with 300 ninth graders and two small schools with 20 ninth graders each. If 70% of the students graduated at the large school and 95% at the two other schools, the student average would be (300x70%)= 210 graduates plus 19 + 19 graduates, so the "weighted average would be 248/340 = 72.9% for the county.

The data for the series 2009 -2013 is unweighted. This means it averages all the individual school graduation rates in a county, rather than taking all the ninth graders in the county and how many of that cohort graduated 4 years later.  In the above example, the graduation rates of the three schools would be averaged (70% +95% +95%)/3 = 86.6%.  86.6% would be the unweighted average.
