The district is forced to come up with a budget months before the state approves their budget, so they don't even know if they are going to get the money they need.
When money is low, they have gone to the community several times trying to pass a property tax to raise funds to keep teachers and maintain their facilities. The community has refused to fund the school each time.
The district is constrained by their contract with the teachers which forces them to keep the most incompetent and highly paid teachers and get rid of the good but non-tenured new teachers (which are the ones that the students want to have).
The way schools are funded are a major source of the problem. For example, they are funded per student with no regard for facilities, transportation, or other fixed costs.
Lastly, there are too many crippling regulations that don't allow for flexibly to meet the various needs of students in varying districts. What works in the large LA County district is just not going to work in rural northern California.
Throwing more regulations, tests, money, etc. at the system is not going to fix it. I really wish that a large group of educators (K-12, post-secondary), administrators, parents, etc. could get together and work out something different, perhaps even radically different.
