While there doesn't appear to be information about scholarships on the school's website, it's definitely worth contacting the school directly to inquire about what financial assistance might be available. You can reach Cherry Valley Brethren Pre-School either via email or at (951) 845-3089.
If you're looking for low-cost preschool in your area, I'd also recommend looking into Head Start, a federally funded early childhood education program that's free for qualifying families.
Hope this helps!
