School districts are hiring more teachers and expanding class sizes to accommodate the anticipated influx. Officials are unsure how many of the nearly 50,000 Georgia eighth graders who failed the math portion of the Criterion-Referenced Competency Tests will take classes this summer.

Fifth and eighth graders must pass the math CRCT before they can be promoted to the next grade. Summer school is not required to retake the test, but it is recommended.

The state has promised $1.4 million to help the districts offset the costs.

State officials say they expected more students to fail because the test was tougher this year.
