The Maryland School Assessment is reported with three performance standards -- basic, proficient and advanced.

For mathematics, the standards are defined as follows:

* Basic: Students at this level demonstrate only partial mastery of the skills and concepts defined in the Maryland Mathematics Content Standards.

* Proficient: Students at this level demonstrate an understanding of fundamental grade-level skills and concepts and can generally solve entry-level problems in mathematics.

* Advanced: Students at this level can regularly solve complex problems in mathematics and demonstrate superior ability to reason mathematically.

The following are the mathematics scores for the three public school systems in Southern Maryland. The scores represent the percentage of students performing at each level. The first number in each listing is this year's score; the second number is the 2004 score.
