Students, teachers and school administrators across the state experienced some frustration this spring due to Georgia Milestones testing technical errors. CTB/McGraw-Hill, the test developer, will reimburse the state for these troubles with $4.5 million in services at no cost to the Georgia Department of Education, according to a release from the department. The services include the assurance that future administrations of the test will not suffer the same issues, which included content errors, freezing and technical disruptions and delays.
