Although there is no California law or case requiring a parent to be at home during periods of instruction, such a policy would probably be upheld for a child under 18. The one federal court of appeals that addressed this question found that such a policy does not violate the Individuals with Disabilities Education Act (IDEA) or Section 504. [Daniel O. v. Missouri State Board of Ed., 210 F.3d 378 (8th Cir. 2000).]
