Description¶
A standardized group intelligence examination series developed by Walter F. Dearborn and colleagues for measuring pupils' intelligence relative to age and grade norms.
Components¶
Claims¶
- The NRC committee trialed some twenty tests on five thousand children and produced two series of group intelligence tests of high reliability [+W]
- Group scales allow examining fifty or a hundred children in an hour, whereas individual Binet testing restricts use to special cases [+W]
- Half-year standards were set so the median child of each age had an IQ within 0.90 to 1.10 in every community, and discrepancies were small [+W]
- The assumption that children of a given age have a median age exactly at the half year was found incorrect in the standardization sample [+W]
- The customary large-sample lumping method of standardizing tests produced complaints that whole classes were placed too high or too low and that rankings across tests diverged [+W]
