The key to the problem

Juárez Correa noticed the kids staring at him, but he wanted to make sure he understood the report. He took a moment to read it again, nodded, and turned to the kids.

“We have the results back from the ENLACE exam,” he said. “It’s just a test, and not a great one.”

A number of students had a sinking feeling. They must have blown it.

“But we have a student in this classroom who placed first in Mexico,” he said, breaking into a smile.

Paloma received the highest math score in the country, but the other students weren’t far behind. Ten got math scores that placed them in the 99.99th percentile. Three of them placed at the same high level in Spanish. The results attracted a quick burst of official and media attention in Mexico, most of which focused on Paloma. She was flown to Mexico City to appear on a popular TV show and received a variety of gifts, from a laptop to a bicycle.

Juárez Correa himself got almost no recognition, despite the fact that nearly half of his class had performed at a world- class level and that even the lowest performers had markedly improved.
