The DIAGNOSTIC EVALUATION OF LANGUAGE VARIATION (DELV) has been created so that speakers of non-mainstream dialects will not be penalized for the use of those dialects in the language testing situation. The DELV Screener and DELV-Criterion Referenced edition were standardized in 2002 and published in spring 2003. A norm-referenced edition, standardized on a nationwide sample of African American children ages 4 to 9, will be published in July 2005 by
The Psychological Corporation (TPC) of San Antonio, TX.
