## Outcome Assessment Strategies

Assessment must include:

- Attend 80% or more of class meetings for pass consideration.
- At least one or more of the following measures:
- Quizzes
- Homework
- Portfolios
- Group Projects
- Individual Projects

The course is only offered using the Pass/No Pass option.
