STOCKPORT, Ohio (AP) -- New standardized tests based on the national Common Core standards are being introduced in U.S. schools.
The first students to take them are in Ohio beginning Tuesday.
The reading and math tests replace traditional spring standardized tests and most students will take them by computer or electronic tablet.
They were developed by two groups of states and will be given to about 12 million students in 29 states and the District of Columbia.
Some school administrators worry their schools will have Internet connectivity problems, but the tests have a paper option.
The Common Core standards, which arose from the federal No Child Left Behind law, have been adopted in more than 40 states and spell out what reading and math skills students should master in each grade.
