Core vocabulary is one of the appealing subjects in special education. In this study, some researches related to core vocabulary is reviewed. Then, utilization of core vocabulary for students with special needs is elaborated.
The research is descriptive-analytic. Researches on Farsi indexed since 1973 in Scientific Information Database, The Comprehensive Portal of Human Sciences, IRANDOC and researches on other languages indexed since 1928 in ERIC, Google Scholar were reviewed.
The best method for estimating core vocabulary is to combine different corpora and extract high frequent words )more than 80% in the corpus(. Utilization of the list of core vocabulary in developing screening test and intervention programs is the next phase.
Utilization of core vocabulary can be both in developing screening tests and intervention programs. Thus, a standard for vocabulary screening of special students and adults and consequently the processes for intervention )a special kind of word regime as the language support( can be set. Core vocabulary interventions are efficient for students with intellectual disability and specific language disorders and also deaf and hearing impaired students.
