Developmental screening tools have improved over the years, and instruments that

are extensively tested and easy to use in an office setting are now available. Plans

should choose a tool that has a documented high level of accuracy and effectiveness. 

Measures of accuracy and effectiveness include:

Specificity (percent of normal children that are correctly identified)

Sensitivity (percent of children with developmental disabilities that are correctly

identified)

Reliability (the extent to which a tool measures consistently)

Good developmental screening tests that document the validity of results have sensi 

tivities and specificities of 70 to 80 percent. This is largely because of the nature and

complexity of measuring the continuous process of child development.
