Should we level books?

Leveling books for children has both positive and negative aspects, as most things do in life. Experienced teachers might be able to recognize when a student is reading at, above, or below his reading level. However, newer teachers might find this more difficult. Leveled books are useful in this way of providing a guide for teachers (and parents) when choosing literature for their lessons. That beings said, I don't believe that children should be restricted to their supposed "level." Many students can read above what their level suggests. They should be granted the freedom to choose the books the read. However, some students choose books that are below their level. This can pose problem, as these books do not provide the student with challenging vocabulary or other adequate material. It would be necessary, in this case, for a more appropriate book to be given to the student. That being said, an occasional lower level book of their choosing would not harm them. A major problem with leveling books is that it can cause self-esteem issues in students that are slower learners. They may notice their peers reading higher level books, while they continue to struggle with a lower level book, thus reducing their self-confidence. It is a difficult topic and one that has yet to be resolved. While students need to read a challenging book, reading a book they can not comprehend will not support their learning. Perhaps, if we simply switched the term from "level" to "recommendation," the negative connotation might pass. Overall, I believe that leveling books is appropriate to use as a guide, not as a standard for students.
