Graduation rates in Michigan – and Detroit’s main district — are up, but are most students ready for college?

The state superintendent had some good news to share Wednesday about last year’s four-year graduation rates: They are at their highest level in years.

What’s not clear is whether new graduates are being adequately prepared for college.

Slightly more than 80 percent of the state’s high school students graduated last year, an increase of about half a percentage point from the previous year. It was news state education leaders cheered.

“An 80 percent statewide graduation rate is a new watermark for our schools. They’ve worked hard to steadily improve,” state Superintendent Brian Whiston said in a statement.

“This is another important step in helping Michigan become a Top 10 education state in 10 years. We aren’t there yet, so we need to keep working and moving forward,” he said.

But statewide, the number of students ready for college based on their scores on the Scholastic Aptitude Test was about 35 percent, underscoring the fact that graduation rate is not necessarily a great measure of school success. Schools looking to raise graduation rates can find ways to make it easier for students to earn credits toward graduation and, unlike some states, Michigan does not require students to pass graduation exams.

The result is that more students are graduating from high school — but might not be ready to do college work.

In Detroit, graduation rates in the city’s main district remained largely steady, with a little more than three-quarters of its students graduating after four years. But the number of students who were ready for college dropped almost a point to 12.3 percent last year. While most students take the SAT in 11th grade as part of the state’s school testing program, that’s an indication students graduating from high school may not have been adequately prepared for college.

The state dropout rate remained largely unchanged at almost nine percent.

Detroit’s main district had the highest four-year graduation rates compared to other large districts, but more district students dropped out of school than in the previous year. More than 10 percent of Detroit students dropped out of high school in the 2016-17 school year, a slight increase from last year, according to state data.

Nikolai Vitti, Detroit’s school chief, said the report should motivate the district to ensure students are graduating at higher numbers, and are college ready when they leave high school.

“We are focused on creating a college going culture in our high schools by expanding accelerating programs, such as IB, dual enrollment, AP, and Early College,” he said. “We have already expanded SAT preparation during the school day and intend to offer classes within the schedule for this focus with 10th graders next year.”

Focusing on strengthening basic skills among elementary and middle school students also will better prepare them for college after graduation, Vitti said.

“Most importantly, if we teach the Common Core standards with fidelity and a stronger aligned curriculum, which we will next year at the K-8 level for reading and math, our students will be exposed to college ready skills and knowledge,” he added. “We look forward to demonstrating the true and untapped talent of our students in the years to come.”

But in spite of steady dropout rates and relatively low college readiness numbers, state officials were upbeat about the graduation results.

“This is the first time the statewide four-year graduation rate has surpassed 80 percent since we started calculating rates by cohorts eleven years ago,” said Tom Howell, director of the Michigan Center for Educational Performance and Information, which tracks school data. “This increase is in line with how the statewide graduation rate has been trending gradually upward.”
