Stop segregating them because it's cheaper or pays more. Hiring the cheapest teacher is not cost effective. It's been going on for years at the expense of the children. AISD should start fresh and plan cost saving programs that are good. Spend money on programs that work.
Accountability is a problem.
All principals should be drilled and trained in sound money management principles. Some barely follow their basic tables of organization. Some overspend bond money they didn't have and included in their bond committee proposals in spite of the caution exercised by community members that sit on these committees. There is a paucity of complete detailed information provided to the public. The same is true for Central.
