The VAS stimulus books are available digitally, for use on your tablet, or on paper, for traditional administration. Free training is available. PAR offers a free training course to assist users in becoming acquainted with the measure. This interactive online presentation is available on demand through the PAR Training Portal. Evaluate hard-to-test individuals. Ideal for use with nonreaders, beginning communicators, or people who have reading or written language impairments, the VAS requires no reading or writing.
