Concentration: You can select any Concentration you want within the Biology Department (or any major at Cal Poly for that matter) and still be qualified for the credential.
GPA: Maintain an overall GPA above 2.67. If you had some poor quarters that brought your GPA down it is also possible to calculate your GPA based on your last 90 units (your last 90 unit GPA must be above 2.75).
Courses: Take SCM 300 in the Spring quarter or EDUC 300 any quarter. Either class fulfills the prerequisite for the credential program. Both classes involve about 45 hours of observation in middle school or high school classes. Talk to your advisor about using SCM 300 or EDUC 300 as part of your degree.
