We study the variance of sums of the indicator function of square-full polynomials in both arithmetic progressions and short intervals. Our work is in the context of the ring $$mathbb {F}_q[T]$$Fq[T] of polynomials over a finite field $$mathbb {F}_q$$Fq of q elements, in the limit $$q
ightarrow infty $$q→∞. We use a recent equidistribution result due to N. Katz to express these variances in terms of triple matrix integrals over the unitary group, and evaluate them.
