PROVIDENCE, R.I. (AP) _ Rhode Island's chapter of the American Civil Liberties Union plans to sue over the state's testing requirements for high school graduation.
The ACLU has scheduled a news conference Wednesday morning to discuss the lawsuit, which challenges the use of the New England Common Assessment test.
Starting with the Class of 2014, showing partial proficiency on the NECAP is scheduled to become a graduation requirement.  
The ACLU says about 4,000 students are in jeopardy of not graduating based on their test scores.
Students who fail the test during their junior year are allowed to take it again as seniors or take an alternate test.
But opponents of the NECAP say it doesn't accurately measure student achievement and many schools aren't adequately preparing students to take the test.
