Murray Independent School District

The word "independent" denotes that it is separate from any district operated by a county—in this case, Calloway County, of which Murray is the largest city and county seat.

It is organized by department, and school days are structured into seven periods.

In each department there may be integrated, accelerated, and advanced placement classes.

Students are required to earn a minimum of 22 credits for graduation.

Students can elect to earn the Kentucky Commonwealth Diploma, which is a more comprehensive diploma as it requires the student to take four classes for college credit (AP classes).
