The number of biracial school-aged youth has continued to increase dramatically (Jones & Smith, 2001), and has drawn timely attention to the extent to which practicing school counselors address biracial youths' concerns in a culturally competent manner. This study examined the perceptions of a nationally-based random sample of 203 White school counselors who provided their assessment of a students functioning (i.e., GAF) and case conceptualizations (i.e., multicultural case conceptualization ability [MCCA]; Ladany et al., 1997) in response to a summary of a fictitious student. In the summary, the student was identified as White, Black, Asian, Biracial Black-White, Biracial Black- Asian, or Biracial Asian-White; the student summaries were identical less the racial background of the identified student. Potential differences in assessments of students' functioning and inclusion of racial-cultural information in case conceptualizations were examined across the six student conditions, which yielded non-significant results. Nearly 89% and 93% of participants failed to address race or culture in their conceptualizations of students' presenting concerns and treatment conceptualizations, respectively. Additionally, school counselors' denial of racism (i.e., color-blind racial attitudes) was shown to moderate their inclusion of racial-cultural information in their treatment conceptualizations across students' racial backgrounds. Implications of the findings, future research directions, and multicultural education in school counseling curricula are discussed.
