Assessment and Requirements

Assessment of Academic Achievement

Methods for measuring achievement of objectives:

  1. Tests will be given throughout the semester.  Tests scores represent 65% of the course grade.
  2. Laboratory activities and performance exercises will be done where students will demonstrate an understanding of practical applications.  These will make up 10% of the course grade.
  3. A written final exam will be given which will represent 25% of the course grade.

Texts, handouts, and/or workbooks will be determined by the TAE Department.
