### Goals

- Master's degree students develop a broad knowledge of mathematics and a degree of competence in one field within mathematics.
- Doctoral students develop a broad knowledge of mathematics; learn about the roles of instruction, service, and research in the mathematical profession; and study a mathematical topic in depth, reporting their findings in a thesis that meets professional standards.
- Graduate students find employment in teaching or industry.

## Doctor of Arts in Mathematics

The Doctor of Arts in Mathematics is designed to prepare the student for a teaching career in institutions of higher learning. The program emphasizes broad competence in mathematics rather than specialization and makes provision for classroom teaching experience.

## Master of Science in Mathematics

The Master of Science in Mathematics is designed to provide a broad and in-depth background and prepare the student for further study at the doctoral level or for an industrial or academic career.

## Master of Arts in Mathematics for Secondary Teachers

The Master of Arts in Mathematics for Secondary Teachers (MAMST) is designed for people with a bachelor’s degree who hold a secondary school teaching certificate for the teaching of mathematics and have at least three years of full-time teaching experience. The objective of the program is to enhance the mathematical training of secondary teachers and to equip such teachers with a broad and modern background in mathematics.
