Etazo is a revolutionary way to collect and manage assessment data. Students use an iOS device to enter their assessment responses - then after synchronization - reports are immediately available for teachers and administrators. This application is the mobile version of the Tango Benchmark Appraisal System and requires the Tango Item Bank Editor for the creation of answer keys. Reports for educators include those by student, class, teacher, building and district. Item analysis by question and assessment standard are available along with other reports critical to making valid decisions based on assessment results.
