One page short form versions of each of these instruments have also been developed. The infant form is comprised of an 89-word vocabulary checklist with separate columns for comprehension and production. Two equivalent versions of the toddler form each contain a 100-word productive vocabulary checklist and a question about combining words. The short forms can serve as an alternative to the full versions when rapid assessment of a childs language level is needed or when parental literacy is low. They may be ordered at a cost of $.35 each from Larry Fenson, Department of Psychology, 5500 Campanile Drive, San Diego State University, San Diego, CA 92182-4910. Phone: (619) 594-6614.
