William was born in 1287 in the village of Ockham (probably the village of that name near London in Surrey). He probably entered the Franciscans at London as ''puer oblatus'', when he was seven or eight, where he would have received instruction in grammar and elementary logic, as well as an introduction to Franciscan life. After his novitiate, he embarked on more advanced studies of logic and philosophy in London, and he was ordained subdeacon at the age of eighteen in 1306. He continued to study philosophy and theology until he was admitted to the lectorate program at the Oxford ''studium'' in 1310.

He began studying theology at Oxford, probably in 1317, when he began the requisite two-year period of lecturing on Peter Lombard's ''Sentences''.  On 18 June 1318 he was ordained priest in Oxford and received a licence to hear confessions.

After this, probably in 1321, he is thought to have taught philosophy at the Franciscan ''Studium Generale'' in London, and to have worked alongside Walter Chatton and Adam de Wodeham (his foremost disciple)<ref>The view that Ockham was resident in London between 1321 and 1324 was first proposed by Father Gedeon Gal in the introduction to the critical edition of Ockham's Summa logicae in 1974 (Introduction to ''Ockham, Summa logicae'' (Opera Philosophica 1), ed. Ph. Boehner,G. Gal, and S. Brown. St. Bonaventure 1974, but was challenged by Courtenay, 1990.  Courtenay regards the 'London period' as probable, but far from certain.</ref>. From this 'London period' date most of Ockham’s important philosophical works, his eucharistic treatises (''De quantitate'' and ''De Corpore Christi''), and his great work, the ''Summa Logicae''.
