What is the class size of the classes?

How does class size affect student achievement?
Among the schools without missing data, a “one-student” reduction in class size is associated with smaller achievement gains than those found in the most influential studies of class size. In other words, the research typically concludes that smaller classes are associated with higher student achievement.
What is considered small class size?
In research on early elementary school students, small classes usually mean fewer than 20 students, while for high school students the definition of “small” classes is usually somewhat larger. There are similar variations in what constitutes small classes for college writing instruction.
Is smaller class size better?
A new statistical analysis of data from a long-term study on the teaching of mathematics and science has found that smaller class sizes are not always associated with better pupil performance and achievement. With smaller class sizes, teachers can more easily maintain control and give more attention to each pupil.
