According to the Oregon law, home school students must be tested by the end of grades 3, 5, 8, and 10. After tenth grade, there are no testing requirements, not even for the CIM/CAM. Diplomas are not awarded to home school students by the state so whether or not your student has earned a diploma is left up to your discretion. We do, however, suggest that your student take either the GED, SAT or ACT.
The GED will be required by most employers if your student is not college bound; they just want to make sure that they are hiring a person who has completed high school. The SAT or ACT are more for college bound students. Almost without fail the college your student is applying to will request these test scores. This is to assure that the student is working at the caliber they require, and is also quite helpful for getting scholarships. If your student knows where he/she wants to apply, we would suggest calling the office of admissions there and asking which test they would prefer, some lean more toward the ACT, some prefer the SAT.
