In a "Handbook of Mental Tests" Professor Kuhlmann, in 1922, published a new age level scale of intelligence tests representing an extensive revision of scales hitherto in use. While there are points of resemblance to the Stanford-Binet scale, there is such divergence as to constitute this a new scale.
The scale includes tests for ages as low as the 6 month level. It has five tests each for the 1 year, 18 month and 2 year levels. From here up to the 10 year level there are eight tests for each year. These do not differ markedly from the Terman tests except for the addition of some tests requiring speed and accuracy. For instance, the child is to fold a paper as the observer has folded one, and, in another, the child is to tell how many times the observer has tapped on the table, the taps being given irregularly.
