IV. How Do Researchers and Clinicians Measure Language Development in the School-Age
Years and Beyond?
A. Assessment Types
1. Practitioners may use formative evaluations to inform potential language-learning
activities, or to measure the language-development process.
3. Screenings are brief assessments usually performed at the beginning of the school
year to help identify students who need extra assistance in certain areas.
5. These assessments are typically used to identify the presence of a language disability.
6. Progress monitoring assessments are conducted routinely to document a child’s rate
of improvement in an area and to monitor the efficacy of curricula and interventions.
B. Assessment of Language Form
1. Measurement of Phonological Development
2. Measurement of Syntactic Development
a. To measure syntactic development in the school-age years and beyond, examiners
can use language samples, elicitation procedures, judgment tasks, and
standardized measures.
b. Language samples are useful for measuring advanced syntax.
c. To do so, the researcher or clinician segments the transcript of spoken or written
language into communication units (C units) or terminable units (T units).
d. C units and T units both consist of an independent clause and any of its modifiers,
such as a dependent clause.
e. The difference between C units and T units is that C units apply to oral language
analysis; they can include incomplete sentences and sentence fragments.
h. Elicitation procedures are also useful for examining advanced syntax, including
complements, verb clauses, multiclause utterances, question forms, and negation.
i. There are judgment tasks appropriate for use with school-age children and adults.
j. One such task is the graded grammaticality judgment paradigm.
C. Assessment of Language Content
1. Measurement of Lexical Meaning
