A bill under consideration by state lawmakers could result in Tennessee students having a tougher time getting good grades. Officials say the bill could make TNReady standardized tests score a larger percentage of student’s final grade in some cases. Currently, TNReady test scores make up 10 percent of the final grade for students in 3rd through 8th grade. That percentage could jump to 15 percent next school year. The proposed bill gives more power to local school boards to decide how much weight the standardized tests will have. It gives them the choice to make it a quarter of a student’s final grade. It also gives schools the option of completely ignoring scores for grades 3 through 5. For students in grades 6 to 8, the comprehensive test scores have to account for 10 to 25 percent of the student’s final grade. The bill also instructs the state to hand over test scores on time. If they aren’t given to teachers on time, teachers don’t have to factor them into final grades. The bill has passed the Tennessee House and will be discussed this week in the State Senate education committee.
