The alternate‐forms and alpha reliabilities of the Teacher Stress Inventory were investigated based on the responses of two groups of 138 teachers. Reliability estimates ranged from .43 to .94 for the TSI subscales and .71 to .94 for the TSI whole scale, indicating high stability and equivalence for the stress factors across immediate, one‐day, one‐week, and two‐week intervals using two different TSI short forms. Between‐forms correlations were larger for the immediate sample than they were for the interval samples. Short‐form TSI alphas ranged from .76 to .90.
