From my hub, "Common Core Standard"
States adopting the common core standards are required to measure student achievement in the 2012-2015 school year. While a common assessment has not been agreed upon, two consortiums have proposed differing online assessments. The decision for which assessment is to be used rests with each state or territorial school board. Arizona and 25 other states have chosen the computer based PARCC assessments to be conducted throughout the school year. The SMARTER Balance consortium, comprised of 31 states has chosen adaptive online exams.
