A middle planar member is secured to the front planar member. The middle planar member has at least one aperture therethrough. A plurality of slide members with indicia responsive to selected questions on the front side and bar code indicia on the back side. The indicia on the front side of the respective slide members is aligned with the response aperture on the front planar member. A rear panel member is secured to the middle planar member. The rear panel member has a bar code indicia aperture in parallel alignment with the response aperture, so that when the indicia is aligned with regard to the response aperture, the response in bar code is aligned with the bar code aperture on the rear planar member. A transparent film is secured to the front planar member, with a first opening to receive a removable question portion therein. A second opening may be provided in the transparent film to receive a removable rating indicator therein.
