The state Department of Education is giving Oklahoma sixth graders the option to retake their state reading test.
Schools say there was an error in the instructions for the test, making it unclear that students were supposed to continue to the next section of the test.
Districts say the confusion may have led to some students submitting incomplete tests.
Many districts are allowing parents to call to schedule a retest.
Computer errors led to interruptions in state testing in 2013 & 2014. State Superintendent Joy Hofmeister said a recent survey of 10,000 parents showed testing to be their number one concern about Oklahoma education.
This retake follows one at Skelly Elementary where two teachers are accused of violating strict rules on how testing is handled and test questions and answers protected.

Sources say the teachers wrote down questions and answers then gave them out to other students.
The district said because it's uncertain which students might have gotten help, the entire sixth grade at Skelly has to retake their math and reading tests.
TPS plans to fire the teachers for breaking the rules. The school board will set hearings where the teachers can fight the dismissal.
