In short, the project releases the large quantity of data collected in the Specific Language Impairment (SLI) Epidemiologic study. The National Institute on Deafness and Other Communication Disorders (NIDCD) created this outreach as a means to fully utilize research data gathered with its support.

Because of the NIDCD's generous funding, the data set is available without charge.

Those interested in this data set are likely child language researchers, particularly new or aspiring investigators who may not yet have support to carry out a large study such as this; those who need to boost their population sample size; or those interested in using the data for pilot studies. These data may also be used by professors interested in developing an educational exercise for their students.

Before requesting the data set, you should:
1. Read the description of the project to gain a general understanding of the goals and outcomes of the study.

2. Carefully read the lists of published articles and poster presentations to learn the analyses and conclusions presented/published by the CLRC. You would not wish - of course - to waste time by duplicating work already presented by the original research team.

3. Understand how the SLI data were collected.

Your final step is a formal request for the data. You may make this request by completing a simple, on-line, registration form. However, please be aware that registration implies your agreement to the following conditions of fair use.

Once your application form has been received and approved, a CD with the full data set and instructions for its useage will be mailed to you.
