Abstract: We will show that tightness, character, sequentiality, and Frechet-Urysohn property are discretely reflexive in compact spaces, i.e., if $$X$$ is a compact space in which the closure of every discrete subset has a property $$P$$ from the list  $$tightness \leq \kappa, character\leq\kappa, sequentiality, Frechet-Urysohn property$$, then $$X$$ has the property $$P$$.
