In elementary school, Guadalupe Quintanilla was often referred to as a “slow learner” by her teachers. But she really wasn’t slow at all. She just didn’t understand the language used in the classroom. Her problem was that she didn’t speak English. So she left school after the fourth grade.

When Guadalupe grew up, married, and had children of her own, she knew that her children were clever. But some of their teachers didn’t think so.
