TOPEKA, Kansas (AP) — The Kansas Board of Regents has approved an increase in the cost of taking the General Educational Development exam.

The Wichita Eagle reports that the board on Wednesday unanimously approved increasing the fee for taking the GED from $68 to $85.

The fee increase takes effect July 1. Gary Alexander, vice president of academic affairs for the regents, said the price increase was prompted by increases in the cost of giving the test.

The GED, also known as the general equivalency diploma, is a battery of tests that allow people who didn’t finish high school to demonstrate their proficiency in the skills required of a high-school graduate.

The five tests include math, reading, writing, science and social studies.
