A recent meta-analysis by Fishstrom and colleagues examined the effects of academic interventions on academic achievement and academic anxiety in students in kindergarten to Grade 6.

The meta-analysis of 11 studies included 34 effect sizes, of which 17 were for academic achievement outcomes, and 17 were for academic anxiety outcomes. The results revealed statistically significant differences favoring academic treatments (g = 0.63, k = 11), consistent with existing research. In contrast, no statistically significant differences were found for academic anxiety outcomes (g = -0.06, k = 11).

Despite the limitation of the small number of studies with elementary school students that met the criteria, and the difficulties in measuring academic anxiety, the study suggested that academic anxiety is not necessarily relieved by academic interventions.
