Japan

Monbusho reports the number of hours of instruction per year for Japanese 13-year-olds as 1,050. However, the report states that one hour is equivalent to 50 minutes of instruction. Therefore, to make the Japanese figures comparable to the hours of instruction reported in the International Assessment of Educational Progress for other countries, the number of hours in the Japanese school day was multiplied by a ratio of 50 minutes to 60.
