We evaluate constructive Zermelo-Fraenkel set theory (CZF) of intuitionistic logic. Of the eight CZF axioms, only the induction scheme is tautologous. From CZF axioms for infinity, set induction, and extensionality the deduction of one set denoted ω is not tautologous. An equation for extended Church's thesis (ECT) is not tautologous. This supports previous work that intuitionistic logic is not tautologous.
