Years ago, I was told that one of the reasons that American Indian educational issues are not studied by IES/NCES (Institute of Educational Sciences/National Center for Education Statistics) is because American Indians represent too small a proportion of the population and they are not a politically “hot” area for study. I was still a graduate student at the time, and was participating in a government-sponsored workshop on using the NCES databases–specifically the NELS:88 (National Education Longitudinal Study of 1988) database for research. Clearly, active study of educational issues related to this very important (to me) small population has not changed.
However, there is a site now that dedicated to American Indians, and it can be found through the link below. If you are interested research or research results about American Indian education issues, this may be the place to start. If enough interest is generated in the site, maybe issues related to indigenous populations will hit the forefront.
