Mexicans are getting shocking news about their public schools, 11 percent of which don't have bathrooms.

That figure rises to almost one-third in poor states like Oaxaca, Guerrero and Chiapas.

About 24 percent of teachers tested at grade schools and middle schools either failed teacher evaluation tests or didn't show up for testing.

The Education Department says the teachers who failed will be given another try.

But Education Secretary Aurelio Nuno said Tuesday 3,360 teachers who didn't show up twice for testing will be fired.

About 45 percent of the approximately 146,000 teachers tested got good or excellent ratings. The rest got adequate scores.

Mexican public schools are poorly funded, and teachers' unions often control hiring and firing.

The evaluations were introduced last year as part of an education reform.
