* Evidence of literacy: The existence of the Indus script, found on seals, pottery, and other artifacts, strongly suggests a degree of literacy within the civilization. The widespread use of standardized weights and measures also implies a need for record-keeping and potentially formalized education in these systems.
* Specialized crafts and skills: The sophisticated urban planning, advanced craftsmanship (e.g., pottery, metallurgy, bead-making), and standardized brick sizes indicate specialized training and apprenticeships. This suggests a system for passing down skills through generations, possibly involving a form of vocational education.
* Potential for formal institutions: While there is no direct evidence of schools or formal educational buildings, the organized nature of the cities and the complexity of their systems hint at the possibility of institutions dedicated to teaching, though their exact nature remains unknown.
* Religious or ritualistic learning: The discovery of artifacts related to religious practices, such as seals depicting deities or ritual objects, suggests that religious knowledge might have been transmitted through oral traditions or within specific groups.
In summary, while the specifics of Indus Valley education are unknown, evidence points to a system likely involving:
* Literacy and numeracy: For record-keeping and administration.
* Vocational training: For specialized crafts and skills.
* Possibly formal institutions: Though the nature of such institutions remains unknown.
* Oral transmission of knowledge: Particularly for religious or cultural practices.
Further research and, most importantly, the decipherment of the Indus script, are crucial to understanding the intricacies of their educational system. Until then, our understanding remains limited to educated inference from the archaeological record.
