Very different from the Online Learning Policy is Board Policy C04.00, Alternative Courses of Study.
With the Online Learning Policy, the Board grants the superintendent the authority to determine which courses earn credit and which do not.
In Policy C04.00, the Board retained control of the question. Any school that wants to award credit to students via an Alternative Learning Experience must annual present written policies to the Board for review and approval.
The difference is rooted in the state law authorizing Alternative Courses of Study, WAC 392-121-182, which, in Section 2 requires "The board of directors of a school district claiming state funding for alternative learning experiences shall adopt and annually review written policies for each alternative learning experience program and program provider". The law does allow the board to delegate the decision, but Seattle's Policy makes no provision for that.
Oddly, some online courses are covered by the Alternative Courses of Study rule in law, but it is unclear which Board Policy covers them, which would make it unclear who is supposed to approve them.
Here's an interesting consequence of this Policy: any question about what will be required of alternative learning experiences in Seattle (such as compliance with curriculum alignment initiatives) will be determined by the Board, not by the staff.
I think it would be easy for a staff person to impose curriculum alignment rules on NOVA - or any other alternative school that makes use of the alternative courses of study policy, but it would be politically difficult for the Board to do so.
