In holistic scoring, scorers evaluate the effectiveness of responses in terms of a set of overall descriptions of signed communication. The scoring process is holistic in that the score assigned to your signed performance reflects the overall effectiveness of your communication. For the TASC, “signed communication proficiency” is defined as the ability to communicate successfully, both expressively and receptively.
At least three scorers view each taped interview and, working in collaboration, rate your proficiency. Performance at a Level C or higher (Level A or B) is required to pass the TASC. See the TASC Holistic Rating Scale.
