There are 20-30 pupils in the typical experimental class in a public school, as compared to the traditional 30-46 pupils. The private Forest and Caterpillar academies combine students of different ages (such as putting fifth and sixth graders or third and fourth graders together) into classes of ten or so kids.
公立學校各實驗班人數約在二十到三十人之間（傳統約三十人到四十六人）；森小、毛毛蟲部分課程則是混齡教學，五、六年級，或者三、四年級學生一起上，人數約在十餘人。
