COURSE ASSESSMENT

Student success is measured by a variety of assessment techniques aligned with course goals and learning outcomes. Individual faculty members are responsible for designing evaluation instruments to measure student mastery of course goals and learning outcomes and indicating the nature of such evaluation instruments in the instructor’s class requirements.

STUDENT ACCESSIBILITY RESOURCES

Any student with a documented disability needing academic accommodations is required to contact the Student Accessibility Resources (SAR) Office located on each campus to schedule an appointment with the Coordinator of SAR. All discussions are confidential. Because SAR accommodations may require early planning and are not provided retroactively, students are encouraged to contact SAR as early in the semester as possible. SAR is responsible for approving and coordinating all disability-related services. TCC professors will honor requests for accommodation when they are issued by SAR.

SCHOLASTIC DISHONESTY

Students are responsible for adhering to the TCCD policy on scholastic dishonesty as stated in the online student handbook at www.tccd.edu.
