Attended SSHS for 8th - 12th grade, would not have done as well as I have academically had it not been for the quality of teaching and community at that school. If you want your kid to actually be prepared, safe bet here.
Both of my children did extremely well at Shasta Secondary Home School. As high school students, they were allowed to pursue their interests within the guidelines of the curriculum which encouraged them to learn. The staff is wonderful and supportive.
