value: A test score that has been standardized over time, across subjects, and across various international and regional assessments taken at the primary school level. It is calculated by creating a ratio between U.S. primary scores averaged across subjects on all international tests (such as PISA and TIMSS) to average primary scores averaged across subjects on the U.S. National Assessment of Educational Progress (NAEP) approximated to the nearest 5-year time step from 1965-2010. All raw international primary scores are averaged across subjects and approximated to the nearest 5-year interval, averaged across tests, and then multiplied by this ratio. This makes these adjusted scores comparable over time, across countries and across international tests. Primary test scores from countries which only participate in regional assessments are included in the above transformation after being averaged across subjects and then multiplied by a ratio comparing average primary scores across subjects in a given regional test and average primary scores across subjects on an international assessment for all doubloon countries - countries which participate in the same regional assessment and an international test. This makes adjusted primary test scores comparable over across time, across subjects, over countries and over all assessments.

value: Average Adjusted Primary Test Score.

value: A test score that has been standardized over time, across subjects, and across various international and regional assessments taken at the primary school level. It is calculated by creating a ratio between U.S. primary scores averaged across subjects on all international tests (such as PISA and TIMSS) to average primary scores averaged across subjects on the U.S. National Assessment of Educational Progress (NAEP) approximated to the nearest 5-year time step from 1965-2010. All raw international primary scores are averaged across subjects and approximated to the nearest 5-year interval, averaged across tests, and then multiplied by this ratio. This makes these adjusted scores comparable over time, across countries and across international tests. Primary test scores from countries which only participate in regional assessments are included in the above transformation after being averaged across subjects and then multiplied by a ratio comparing average primary scores across subjects in a given regional test and average primary scores across subjects on an international assessment for all doubloon countries - countries which participate in the same regional assessment and an international test. This makes adjusted primary test scores comparable over across time, across subjects, over countries and over all assessments.

value: A test score that has been standardized over time, across subjects, and across various international and regional assessments taken at the primary school level. It is calculated by creating a ratio between U.S. primary scores averaged across subjects on all international tests (such as PISA and TIMSS) to average primary scores averaged across subjects on the U.S. National Assessment of Educational Progress (NAEP) approximated to the nearest 5-year time step from 1965-2010. All raw international primary scores are averaged across subjects and approximated to the nearest 5-year interval, averaged across tests, and then multiplied by this ratio. This makes these adjusted scores comparable over time, across countries and across international tests. Primary test scores from countries which only participate in regional assessments are included in the above transformation after being averaged across subjects and then multiplied by a ratio comparing average primary scores across subjects in a given regional test and average primary scores across subjects on an international assessment for all doubloon countries - countries which participate in the same regional assessment and an international test. This makes adjusted primary test scores comparable over across time, across subjects, over countries and over all assessments.

value: A test score that has been standardized over time and across various international and regional reading assessments taken at the primary school level. It is calculated by creating a ratio between U.S. primary reading scores on international tests (such as PISA and TIMSS) to primary reading scores on the U.S. National Assessment of Educational Progress (NAEP) approximated to the nearest 5-year time step from 1965-2010. All raw international primary reading scores are approximated to the nearest 5-year interval, averaged, and then multiplied by this ratio. This makes these adjusted scores comparable over time, across countries and across international tests. Primary reading test scores from countries which only participate in regional assessments are included in the above transformation after being multiplied by a ratio comparing average primary reading scores in a given regional test and primary reading scores on an international assessment for all doubloon countries - countries which participate in the same regional assessment and an international test. This makes adjusted primary reading test scores comparable over across time, over countries and over all assessments.
