The test Florida educators have been preparing for began Tuesday.
The Florida Comprehensive Assessment Test, more commonly known as the F-CAT measures learning and comprehension for students in the Sunshine State.
The writing portion of the F-CAT was taken Tuesday morning. It's estimated that 19,000 students will take the test this year from grades 3 all the way up to 12.
School officials say they are very optimistic about the students' performances on the test. Thousands of high school seniors are expected to take the F-CAT, and they have to pass in order to graduate.
Seniors won't know their scores until May. Some education officials say there may be lawsuits if diplomas are denied to students who don't pass.
