This Oxfam project involved 74 kindergartens, along with 1,200 NCS students and 170 teachers.
"Comparing scores in pre- and post-tests, K2 students at seed schools have improved by nearly 100%, while K3 students have also improved by a significant 96%. More specifically, assessment scores reflect that children’s pronunciation of Chinese characters has improved three-fold, and their word association ability by a whopping 409%."
