JEFFERSON CITY, Mo. (AP) — Missouri students showed mixed results on the most recent standardized achievement tests.

Test scores for specific school districts are to be released later.

Statewide data from the Department of Elementary and Secondary Education show the percentage of students scoring proficient or advanced in math declined in 2013, but remained steady in communication arts and improved in science.

The Missouri Assessment Program tests are administered annually and are used as part of the state accreditation process for public schools.

State Board of Education Chairman Peter Herschend says the scores show that Missouri schools are not making as much progress as he would like.
