The act of dismissing or discharging; removal from office or employment, or the formal ending of something.
From Old French dismission, from Late Latin dismissio (a sending away), from dismittere; -ion is a Latin-derived suffix forming nouns from verbs.
While 'dismission' is the technically correct Latin-based noun form of 'dismiss,' English speakers prefer the newer 'dismissal' instead—a small victory for the -al suffix over the -ion suffix in modern English vocabulary.
