Determining whether average quality ratings of program sites (Program Site ID) increase from year to year involves first determining the change in the individual program site’s QRIS Score. First, isolate those program sites participating in the QRIS using the data element, QRIS Participation History and select the category “Program site currently participates in the QRIS.” Then, select the time period desired to calculate a change in score. Rating scores should never be overwritten so there should be a QRIS Score for every time a program site was rated. If program sites are not rated every year, scores will have to be collapsed across time periods such that it is possible to compare the most recent score with the previous one regardless of what year the rating actually took place.
To calculate the change in scores, subtract the previous QRIS Score from the current QRIS Score. Negative scores indicate a decrease in rating while positive scores indicate an increase. Divide the number of program sites that increased by the total number of rated sites, for the percentage of sites that increased their quality scores. Average the scores across all program sites to determine the change in scores over time for all sites. Additional elements, such as Early Childhood Setting, can be used to examine changes in QRIS Scores for sub-groups of program sites.
