Investigations into the departmental directorate of education have turned up some revealing findings. Cases of teachers without the necessary profile to teach specialised courses, or an oversupply of faculty with no pupils to teach are two of the violations unearthed.

Teaching positions are for sale in Mexico, and have been for decades. Although seldom discussed, the practice—established by the Institutional Revolutionary Party (PRI) to reward party loyalists—is apparently widespread. The going price for a teaching position in a public primary school is reported to be between $5,000 and $12,000, depending on locale. Teachers who resign can either sell their positions or pass them on to their children. In at least some cases, local governments and the teachers' union supervise the buying and selling process. However, a recent reform effort—the "Alliance for Education Quality" (ACE)—signed by the government and the national teachers' union in May, would base new teacher appointments on merit, via an examination administered by an independent body. Not surprisingly, it has generated a vociferous response at the grass-roots level. Teachers have gone on strike in many states, marching on government offices, closing schools and blocking streets.
