Test re-test reliability is assessed by what?measuring the same individuals at two points in time
Alternate forms reliabilitydifferent forms of the same test

Content validitythe content of the measure is linked to the universe of content that defines the construct

Concurrent validityscores on the measure are related to a criterion measured at the same time
Convergent validityscores on the measure are related to other measures of the same construct
Discriminant validityscores on the measure are not related to other measures that are theoretically different
