RICHMOND, Texas – Hundreds of students in Fort Bend I.S.D. will be undergoing TB testing starting this week.

This before school starts next month.

It's the second round of testing after nearly 700 students and at least 27 faculty at George Bush High School in Richmond were notified they may have been exposed.

It is mandatory for them and begins Thursday.

During the first round last month, 11 people connected to the high school had tested positive.
