What educators are saying

In one classroom, a student looked at the Star CBM Lectura passage before her teacher had even asked her to read it. She immediately had a smile on her face and said, ‘This is real Spanish!’ Students aren’t always excited about testing, but this was a genuine moment of joy in the classroom. When the language is authentic, students can feel it, because it’s part of their identity and their culture.
