The formula that calculates how many seniors graduated from high school in Missouri this past year was recently reformatted, and the numbers were released, according to MissouriNet.

The new numbers show that 80 percent of Missouri seniors graduated from high school this year. The new formula brings the numbers down slightly, as the previous percentage went from 82 percent to 86 percent in the past 10 years, according to the news source.

In addition, many of the small and rural school throughout the state had a 100 percent graduation rate, the media outlet reports.

According to St. Louis Today, changing the numbering system has been something that officials have wanted to do for some time, as comparing Missouri high schools with others across the country was impossible due to the different formulas.

"If we are going to make progress on improving graduation rates, we have to have an honest look at where we are," Daria Hall, director of K-12 policy at Education Trust, a nonprofit group based in Washington, told the new source.
