Gifted Ed Resources
Below are resources for parents and teachers that can be trusted to adhere to high standards for research-based information and advice. All resources are going to have diverse viewpoints and will grow and change as new information comes to light, but these are your best sources.
The place to learn the basics (after finishing my free course!) NAGC provides a wealth of information through position papers, parent tip sheets, and has a directory that you can search. All the information is carefully vetted by experts.
The Belin-Blank Center is a top source of research into practice information. The center engages in research and provides courses in gifted education and programs for gifted students. It is the go-to resource for information about ACCELERATION.
Johns Hopkins CTY as well as CTY Ireland provides resources for parents and educators who are seeking advanced programming for gifted students. They provide courses for students who want to take their education to a deeper level.
The Davidson Institute has a mixture of informational resources and blogs that appeal to parents and teachers working with the upper end of the gifted spectrum. Some of the blogs entries should be compared with other resources, but overall it is an informative site for parents and educators.
The resources tagged as "Advanced Education" provide a wealth of commentary about gifted education policy in the United States. It is essential for advocacy work.
As a general tip, if you getting in deep into learning about gifted children, are searching on Google and find some information that is behind a research journal paywall, send the lead author an email and they will likely send you the article. Researchers want their work read and do not get any of the money from people accessing their work.
