The department offers several programs designed to give the student an insight into the structure and applications of mathematics and statistics necessary for industrial or governmental employment, teaching, or pursuit of an advanced degree in mathematics and statistics. The department also offers minors in Applied Statistics, Mathematics, and Mathematical Biology.

Mathematics faculty members are committed to educating students in the scientific and engineering environment. Through mathematics courses, students will develop their logical reasoning, critical thinking, technical communication and computational skills.

The department serves students in disciplines including the sciences, education, engineering and mathematics, as well as the community, by offering a wide range of interdisciplinary courses.

Students may register for freshman mathematics and statistics courses appropriate to their high school mathematics preparation and/or entrance examination scores as determined by the department.

The department is committed to the success of all students and provides developmental education course work to help students achieve college readiness in mathematics. Depending on readiness measured in part by TSIM scores, students not yet college ready in mathematics are placed in either: MATH 0302 Developmental Mathematics standalone; MATH 0302 Developmental Mathematics co-requisite with a gateway college level course; or NCBM 0101 Non-Course Based Math co-requisite with a gateway college level course. Developmental courses in mathematics (MATH 0302 or NCBM 0101) receive a grade of credit/non-credit, which is not calculated into the student’s grade point average. Developmental courses do not count as part of a degree program. Academic Advisors and the department review each student’s academic record, assess readiness for college mathematics, and determine appropriate placement when students register for mathematics courses. The Center for Student Success Developmental Education Plan, submitted for approval on an annual basis to the Texas Higher Education Coordinating Board, contains details regarding the Texas Success Initiative Placement Measure.

## Undergraduate Certificate in SAS Programming and Data Analysis

### Admission Requirements

The certification is open to all degree-seeking undergraduate students as well as those registered as non-degree-seeking (transient) students. A student must be in good academic standing and may not be on academic probation of any kind. A student must have earned a grade of *B* or higher in a 1000-level introductory statistics course or its equivalent (must receive approval of the certificate director). The course offered at TAMU-K that meets this requirement includes STAT 1342. Students who have not taken a 1000-level statistics course or equivalent may enroll in one of two courses, STAT 4301 or STAT 4303, as a prerequisite to the certificate program. Students who have earned a grade of *B* or higher in STAT 4301 or STAT 4303 will also have that course counted toward one of the three elective courses for SAS certification, provided the instructor of these two courses also covers the corresponding SAS material appropriate for these courses.

### Application Procedure

Students apply to the certification program via an online form accessible on the department’s website. The form is automatically sent to the program director no later than four weeks after the start of the last class in the certificate sequence. A student’s standing relative to the certificate requirements will be evaluated and, if the student is qualified, he or she will be sent specific instructions on required evaluation materials to complete certification. In case the student is not qualified or is deemed to be making insufficient progress toward the certificate, he or she will be notified accordingly.

### Program of Study

The undergraduate certificate requires 12 credit hours consisting of one 4000-level core course and three elective courses selected from the list below with a minimum of a *B* grade in each course. All elective courses are at the 4000 level and have a SAS component. Courses in the certificate program are shown below. Most of these courses will initially be taught as STAT 4390.

Code | Title | Semester Credit Hours |
---|---|---|

Required Core Course | ||

STAT 4390 | Selected Topics in Statistics | 3 |

Elective Courses (Select Three) | ||

STAT 4301 | Biostatistics | 3 |

STAT 4303 | Statistical Methods | 3 |

STAT 4390 | Selected Topics in Statistics | 3 |

Additional courses will be added as needed.
