Tulsa Public Schools To Hold Language & Cultural Service Summit Ahead of the fall semester, teachers with Tulsa Public Schools said they’re dedicated to serving the entire student body. The district held its annual Language and Cultural Services Summit Monday, supporting Native American students and students learning English. More than one in three TPS students speak English as a second language, and more than 75% of the entire Tulsa student body is a race other than white. Educators said the district's practices should reflect this. Blanca Delgado wants desperately to be a part of her kids' lives, including their education. However, language is a barrier for Delgado. While her kids learned English at an early age, it's a work in progress for her.
