The OAA Mental Arithmetic and Abacus Assessment Test is an annual test designed to help students assess their skills in mental arithmetic and abacus.

2020 OAA Assessment Test

Due to the COVID-19 (coronavirus) pandemic, the 2020 OAA Assessment Test has been canceled. This difficult decision was made out of concern for the health, safety, and well-being of our members. Thank you for your patience and understanding, and we hope to host the event next year.
