We characterise regular boundary points of the parabolic $p$-Laplacian interms of a family of barriers, both when $p>2$ and $1<p<2$. Due to the factthat $p\not=2$, it turns out that one can multiply the $p$-Laplace operator bya positive constant, without affecting the regularity of a boundary point. Byconstructing suitable families of barriers, we give some simple geometricconditions that ensure the regularity of boundary points.
