Cross-sectional comparison of mean ITBS scores by age groups (Figure 14), defined by birthdays within six months of April 15, following the practice of the National Assessment of Educational Progress. The article reports the age-group trends are nearly parallel to the adjusted grade trends.

"This study also shows that grouping students by age instead of grade is a viable alternative for tracking their scores. The age groupings mirror the grade group findings, with the greatest improvements among students most directly affected by the policy."
