Twenty Spanish-speaking Mexican-American children were administered the receptive portion of the Screening Test of Spanish Grammar (STSG) and the Spanish version of the Test of Auditory Comprehension of Language (TACL). The correlation obtained between the two tests was not statistically significant. The correlation obtained between 24 syntactical items common to both tests was also not statistically significant. The probable reasons for the nonsignificant correlations obtained are discussed. In addition, a detailed critique of the Spanish version of the TACL is presented.
