#### Learning Outcomes

For student learning outcomes, please see wiu.edu/provost/learningoutcomes.

#### Program Description

The graduate program in the Department of Mathematics and Philosophy prepares students for needed professions in the region and nationwide. The program provides students with a solid graduate level training in the central and fundamental methods of continuous and discrete mathematics. Both the theoretical framework and the applications of these methods will be covered in the core courses. The 500-level core courses have a significant lean toward applications but theory is present; while the 600-level core courses have a significant lean toward theory and mathematical foundation but applications are not abandoned.

#### Integrated Baccalaureate and Master’s Degree Program

Please refer to Integrated Programs for details and program offerings.

#### Admission Requirements

- A minimum cumulative GPA of 2.75 OR
- A 3.0 or higher GPA for the last two years (60 s.h.) of undergraduate work
- 3 letters of recommendation attesting to the applicant’s academic potential at the graduate level
- International students must have an overall TOEFL score of at least 72 or an overall IELTS score of 6.0.

Undergraduate coursework should include courses equivalent to a major in mathematics. Students who do not fulfill the coursework requirements may be admitted at the discretion of the Departmental Graduate Committee with admission usually conditional upon the student filling specified deficiencies. Students who do not fulfill the GPA requirements will not be considered for admission unless they have demonstrated sufficient competence in mathematics coursework (as determined by the Department Graduate Committee) and complete the general part of the Graduate Record Examination (GRE) with Quantitative Reasoning score above the 60^{th} percentile. All applicants are strongly encouraged to take the general part of the GRE, particularly if applying for an assistantship.
