Abstract: We study weighted composition-differentiation operators of order $n,$ $D^n_{ψ,φ}f:= ψ\cdot f^{(n)}\circ φ$ on weighted Dirichlet spaces. Our main goal is to describe the operator-theoretic properties of $D^n_{ψ,φ}$ in terms of the inducing functions $ψ$ and $φ.$ We characterize bounded, compact, and Hilbert-Schmidt class of such operators and estimate their essential norms. Our approach relies on Carleson measures and the asymptotic behavior of inducing functions. Furthermore, we prove that $D^n_{ψ,φ}$ is bounded for all $ψ$ in the space precisely when $\|φ\|_\infty<1$ and $φ$ belongs to the multiplier algebra of the space. Finally, we give norm estimates for particular elliptic inducing functions and provide examples to demonstrate our results.
