COLUMBIA Ė Superintendent Mick Zais says heís disappointed by the declining scores on South Carolinaís last exit exam.


Zais said Friday that while students will no longer take the exit exam, the state must work toward improved outcomes on the two college- and career-readiness tests that replace it.


South Carolinaís sophomores ushered out the final year of the high school exit exam with their worst passing rate since 2009.


Data shows 77.4 percent of first-time test-takers passed both the English and math sections of the High School Assessment Program last school year. Thatís down from 82 percent in 2013 and was studentsí worst showing since 2009.


Education Oversight Committee director Melanie Barton says the overall drop is clearly due to lower achievement in math. The passing rate on that portion fell 5 points to 78.7 percent.


Barton says the law that passed in April eliminating the test had no bearing on the drop.


Education officials say a new law signed in April abolishing the exit exam could partly explain the drop. They suggested some students might have put forth less effort knowing their scores carried no personal consequence.


ďWe donít know the exact extent, but we do think it had something to do with it given the time frame,Ē Dana Yow, spokeswoman for the state Education Oversight Committee, said Thursday.


The new law, signed April 14, ended the 3-decade-old requirement that students pass an exit exam to graduate, starting with the Class of 2015. Students across the state took the High School Assessment Program between April 1 and April 18. By April 1, both the House and Senate had already given the measure overwhelming approval. The final vote was April 9.


Beginning with this school year, the HSAP wonít exist at all. Instead, 11th graders will take two tests considered more useful to studentsí future success, with scores that can go on work resumes or college admissions applications.


Previously, students had to pass both the math and English sections of the exit exam to graduate, initially taking the tests in their second year of high school. Those who didnít pass both on their first attempt had several chances to retake any part they failed.


Under the law, former students who didnít graduate solely because of the exam can petition their school board to retroactively receive a diploma. The petition deadline is Dec. 31, 2015.


Just 7 percent of 2012-13 high school seniors didnít receive a diploma because they couldnít pass both sections before the school year ended, according to the Education Department.


The switch from HSAP follows recommendations by the independent Education Oversight Committee. The nearly $4 million the state has spent on HSAP will be redirected to the other tests.


The law specifies that one will be ACTís WorkKeys, a work-skills assessment system that awards certificates for qualifying scores, from bronze to platinum, which students can take to employers. The state Chamber of Commerce pushed for WorkKeys as a practical test that help match students to jobs.


The other will test for college readiness. That could be either the SAT or ACT college-entrance exam.
