Supplemental Instruction


You can get help with your coursework, develop study strategies and prepare for tests with the help of fellow students through our supplemental instruction program. Supplemental instruction (SI) is a series of weekly study sessions facilitated by a trained student leader. Attendance is voluntary and open to anyone enrolled in the selected course.

Become an SI Leader

The objective of the apprentice position is to develop student leaders in supplemental instruction. Supplemental instruction is an academic assistance program that targets traditionally difficult academic courses in order to reduce rates of student attrition and improve student grades. The apprentice, while working closely with the selected course instructor, plays the key role in this assistance program by helping students integrate course content and learning/study strategies during a number of regularly scheduled out-of-class sessions every week. Apprentices are the model students of the subject, and as such, they present a model of thinking, organization and mastery of the course.


While employed as a supplemental instruction leader, apprentices may not be employed under any other job title at the college (e.g. student worker, federal work study, etc.). The apprentice may be employed for a maximum of nine (9) semesters, consecutive or cumulative, including summer sessions, and may not work more than 170 working days or more than 980 hours during the academic year. Employment is not guaranteed the full nine semesters. The district accepts applications on an ongoing basis and positions are filled on the basis of need and availability. The District has the right to terminate your employment at any time. As an "at will" employee, you do not have reasonable assurance of continued work. Therefore, during breaks in employment you are eligible to apply for unemployment and may file a claim with the Employment Development Department (EDD). Your entitlement for benefits will be determined by EDD and not by the district.


  1. An overall GPA of 3.0 for all course work in the discipline is required.
  2. A grade of "B" or better in the selected course is preferred. In addition, if in the judgment of the selected course instructor the grade of "B" was not earned recently, the selected course instructor will determine content competency.
  3. Prior completion of the course with the selected course instructor is preferred.
  4. Excellent interpersonal and communication skills, as well as maturity, reliability and dependability.

Selection of Courses for Supplemental Instruction

How do we determine which classes get SI?

We want this process to be as fair as possible. Here is the criteria we use:

  1. The course is considered to be a "high risk/barrier" course:
    Definition of High Risk/Barrier Course:
    1. leads to completion of a general education requirement for degree and transfer
    2. enrolls large numbers of students
    3. had course success rates below the Chaffey College average
  2. A qualified leader is available to attend lecture times and hold study sessions at times convenient for the students attending that class.
  3. Adequate funding is available.
  4. It is most beneficial for the program if multiple sections of the course are being taught by the same instructor.
