Labels can be stigmatizing and may lead to stereotyping.
Labeling has the potential of focusing attention on limitations and what a person cannot do instead of on the individual's capabilities and strengths.
Labels can sometimes be used as an excuse or a reason for delivering ineffective instruction (e.g., "Marvin can't learn his multiplication facts because he is intellectually disabled").
Labels can contribute to a diminished self-concept lower expectations, and poor self-esteem.
Labels are typically inadequate for instructional purposes; they do not accurately reflect the educational or therapeutic needs of the individual student.
Labeling can lead to reduced opportunities for normalized experiences in school and community life.
A label can give the false impression of the permanence of a disability; some labels evaporate upon leaving the school environment.
