You realize California thought that different levels of funding was the problem and now almost all schools are funded by the state based on the number of students. More recently the state doubled down on this "we need more money for poor students" philosophy and now disadvantaged students get more funding. Castro Valley schools probably get less funding per student than Hayward. What people don't want to realize is that the most important component of if a school is "good" or not is the student population itself. You can't change this with funding or changes in teaching styles, or testing, etc. You can with forced busing, but that only works for a little while as parents who want a great school for their kids move to locations where busing is not in effect.
