Warren County students will have reason to perform well on the TCAP exams this year provided a measure passes the School Board that makes the tests 15 percent of the student’s overall grade.The measure, which would impact students in grades 3-8, will take effect this school year provided it passes second read. The policy enhancement passed unanimously on first read Thursday night.Presently, students taking the TCAP exam do not have an official grade from the tests. Instead, TCAP is used as a measuring stick for educators and school systems.
