Rainwater Elementary opened in 1994. The school was named after Annie Heads Rainwater, a Carrollton Pioneer.

Rainwater Elementary currently serves 450 students in kindergarten through fifth grade. The staff includes a full-time counselor, behavior specialist, librarian, physical education teacher, music teacher, art teacher, and many part-time support teachers.

The school day is from 7:50 a.m. to 3:10 p.m. for students in Kindergarten through fifth grades. 

The students selected the school colors - purple, teal and indigo blue. They also selected the school mascot - "Hurricanes". Students described the mascot as representing "a strong force with a calm center".  

Students are the center of Rainwater's program. Problem solving and decision making is a strong focus at Rainwater.
