Codes and Frequencies
For sample children age 3 to 17 years who ever had a learning disability, LERNDAGENO reports the number of units corresponding to the time period (months or years) reported in LERNDAGETP. Thus, these two variables should be used together when doing analyses.
For a full list of variables related to learning disabilities in children, see LEARNDEV.
