Learning Disorder NOS - Answer Disorder s that do not meet criteria in any specific
learning disorder. Might include problems in all three areas that together significantly
interfere with academic achievement even though performance on tests measuring
each individual skill is not substantially below what is expected for person's agew,
measured intelligence, and age-appropriate education
Developmental Coordination Disorder - Answer Performance on daily activities that
require coordination are below expectation for age/intelligence level. Need to rule out
general medical condition/mental retardation
Expressive Language Disorder - Answer A. The scores obtained from standardized
individually administered measures of development are substantially below those
obtained from measures of both nonverbal intellectual capacity and receptive language
development. the disturbance may be manifest clinically by symptoms that include a
,markedly limited vocabulary, making errors in tense, or having difficulty recalling words,
or producing sentences with developmentally appropriate length or complexity
B. Difficutlies interfere with academic or occupational achievement or with social
communication
C. Criteria not met for Mixed Receptive-Expressive Language Dx or Pervasive
Developmental Disorder
Mixed Receptive-Expressive Language Disorder - Answer the scores obtained from
standardized individually administered measures of both receptive and expressive
language development are substantially below those obtained from measures of
nonverbal intellectual capacity. symptoms include difficulty understanding words,
sentences, or specific types of words, such as spatial terms
Phonolgical Disorder - Answer Failure to use developmentally expected speech sounds
that are appropriate for age and dialect (errors in sound production, use, representation,
or organization such as sustitutions of one sound for another)
Stuttering - Answer Disturbance in the normal fluency and time patterning of speech
(inappropriate for the individual's age), characterized by frequent occurrences of one or
more of the following: sound and syllable repetitions; sound prolongations; interjections;
broken words; audible or silent locking; circumlocutions (word substitutions); words
pronounced with an excess of physical tension; momsyllabic whole-word repetitions

psychomotor development through first 5 months after birth, normal head circumference
at birth-

areas of functioning. No clinically significant delays in language acquisition although
more subtle aspects of social communication may be affected. During first 3 years of
life, there are no clinically significant delays in cognitive development (express normal
curiosity about environment, have age-appropriate learning skills and adaptive
behaviors other than social interaction).

level of development. Some symptoms have to have been present before age 7. Some
impairment from the symptoms must be present in at least two settings (home, school,
work). There must be clear evidence of interference with developmentally appropriate
social, academic, or occupational functioning.
Attention-Deficit/Hyperactivity Disorder NOS - Answer 1.Meet criteria for ADHD,
Predominately inattentive type but whose age at onset is 7 years or after
2. Clinically significant impairment who present with inattention but whose symptom
pattern does not meet full criteria for disorder but have a behavioral pattern marked by
sluggishness, daydreaming, and hypoactivity
Conduct Disorder - Answer a repetitive and persistent pattern of behavior in which the
