It is always so interesting to me to see how various districts handle things. I have 3 kids. 2 went to a private high school that offered DE on the HS campus for the bargain price of $150 per credit.
My daughter goes to a public school. DE would require a slew of paperwork, approval of GC after receiving 2 teachers recs, the student to provide transportation and pay full price at the Community College which is a 35 minute drive.
