sourceNone: A test score that has been standardized over time and across various international and regional science assessments taken at the primary school level. It is calculated by creating a ratio between U.S. primary science scores on international tests (such as PISA and TIMSS) to primary science scores on the U.S. National Assessment of Educational Progress (NAEP) approximated to the nearest 5-year time step from 1965-2010. All raw primary science international 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 science 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 science scores in a given regional test and primary science 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 science test scores comparable over across time, over countries and over all assessments.

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

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

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