Kindergarten students should be required to attend full days of school instead of

half days. Studies show that the ability to read plays a large role in a child's success
in school. Most schools begin reading instruction in kindergarten. Therefore, all
kindergarteners should simply spend more time in the classroom. This would
guarantee that each of them gains the basic skills necessary to become a
successful reader.

What is the flaw in this argument?
A longer school day alone would not ensure all students' success.
Many schools already require full-day school for kindergarteners.
It is already commonly known that learning to read early is important.

The flaw in this argument is that it assumes that a longer school day alone would guarantee the success of all kindergarteners in gaining the basic skills necessary to become successful readers. However, there may be other factors besides time spent in the classroom that can affect a child's ability to learn to read, such as teaching methods, individual learning styles, and outside support.
