The two main types of problems associated with early identification are false positives and false negatives. A false positive can create needless worry, anxiety, and expenses for families. At the same time, a false positive can result in wasted resources that could be used elsewhere. False negatives are probably more harmful than falso positives because they preclude early intervention.
Early intervention can reduce thr rick for worsening problems and additional disabilities.
The labels, and the consequent stigma often associated with them, created by identification can have a long-lasting effect on the expectaions teachers place on them. This could result in self- learned helplessness if it goes on too long.
