Monastic schools (Latin: Scholae monasticae) were, along with cathedral schools, the most important institutions of higher learning in the Latin West from the early Middle Ages until the 12th century. Since Cassiodorus's educational program, the standard curriculum incorporated religious studies, the Trivium, and the Quadrivium. In some places monastic schools evolved into medieval universities which eventually largely superseded both institutions as centers of higher learning.
Since the cenobitic rule of Pachomius (d. 348 AD) and the sixth-century Rule of the Master and the Rule of St. Benedict, monks and nuns were required to actively engage in reading. This reading took on the characteristics of a school that dealt with both religious and secular subjects. Beginning in the 5th century a variety of abbots took upon themselves the responsibility of educating those who entered the monastery at a young age. The earliest of these monastic schools had more of a spiritual and ascetic focus than a scriptural or theological one, but it has been suggested that these were the qualities that led many monks trained at the monastic school at Lerins to be selected as bishops.
The Roman statesman Cassiodorus had abandoned politics in 537 and later in the century established a monastery on his own lands at Vivarium in southern Italy. Cassiodorus stipulated that his monastery would be a place of study, providing a guide for that study in his Introduction to the Divine and Human Readings (Institutiones), which encompassed both religious texts and works on the liberal arts. Cassidorus set out this program of study as a substitute for the Christian school he and Pope Agapetus had hoped to establish in Rome. In any event, the curriculum that Cassiodorus set out involved the literary study of well-established texts that he had listed in his Institutiones, following the rules that he laid out in his De orthographia.
