Bachelor of Science in Clinical Laboratory Science (B.S.C.L.S.) Major in Clinical Laboratory Science

Minimum required: 120 semester hours

Admission Requirements

  1. University application deadlines are different than the Clinical Laboratory Science (CLS) Program deadline. Any student entering Texas State may declare Pre-Clinical Laboratory Science as their major. It is recommended that students arrange academic advising at least once prior to making application, and, if possible, arrange to learn about the profession through clinical laboratory tours, personal research, and interviewing a practicing CLS professional. Admission and acceptance to Texas State and declaration as a clinical laboratory science major does not guarantee admission to the program. Admission to the program is competitive and selective. The academic sequence begins during the fall semester of the junior year. Students are selected in the spring semester of their sophomore year. Enrollment is limited by student/faculty ratios and clinical placement availability.
  2. The deadline for submission of applications to the CLS program is February 15th. A typical cohort size of 20 students will be admitted. Applicants will be notified of their status by April 30th or sooner. The criteria for student selection for the junior class includes scholastic ability, particularly in the sciences, essays, and a personal interview, and not on the basis of gender, race, color, religion, veteran status or condition of disability, or national origin. Due to performance standards of the profession, students must meet specific ADA standards in accordance with physical and emotional requirements of the academic program to qualify for admission.
  3. Potential applicants are encouraged to complete the University process early (six to eight weeks prior to the CLS application deadline of February 15th) to facilitate review of transcripts during the CLS Program application process.
  4. A minimum overall GPA and science GPA of 2.50; however, an overall GPA and a science GPA of 3.0 is recommended in order to be competitive in the application process.
  5. Science courses require a minimum grade of “C” or higher.
  6. Students must complete the following five prerequisite courses prior to submitting the CLS application: BIO 1330/1130, BIO 1331/1131, CHEM 1341/1141, CHEM 1342/1142, and the mathematics course. Students may only have a maximum of the nine remaining prerequisite hours, with no remaining credit hours in prerequisite science and mathematics courses prior to beginning the CLS Program. While students are encouraged to complete all prerequisite courses prior to admission, the CLS course sequence only offers 10 hours in the first fall semester and 11 hours in the first spring semester. For students requiring 12 hours for full-time status, please contact the CLS Program.
  7. Completion of the CLS application packet for admission is required by the deadline (February 15th).
  8. Successful interview of selected candidate with admission committee is also required.
  9. Other requirements are necessary by clinical placements (e.g. immunization, background check, and drug testing).
