Education in ancient Rome progressed from an informal, familial system of education in the early Republic to a tuition-based system during the late Republic and the Empire.
 The Roman education system was based on the Greek system – and many of the private tutors in the Roman system were Greek slaves or freedmen.
 The system incorporating the Greeks was connected to Athena (Greek) and Minerva (Roman), the Greek and Roman Godess of Wisdom.
 Due to the extent of Rome's power, the methodology and curriculum used in Rome was copied in its provinces, and thereby proved the basis for education systems throughout later Western civilization.
 Organized education remained relatively rare, and there are few primary sources or accounts of the Roman educational process until the 2nd century AD.
 Due to the extensive power wielded by the "paterfamilias" over Roman families, the level and quality of education provided to Roman children varied drastically from family to family; nevertheless, Roman popular morality came eventually to expect fathers to have their children educated to some extent, and a complete advanced education was expected of any Roman who wished to enter politics.
