Legitimate professional development for teachers is necessary. I used the term ‘legitimate’ to exclude programs and services that are profit-based. These are usually little more than infomercials disguised as professional development. Here, there is no check and balance. There is no blind peer review of the information provided. Only the information that supports their product or service is presented. Information that does not is not. The best example of this is LETRS professional development for teachers. As described in earlier chapters, there is no legitimate research provided to suggest that using LETRS (a) enhances students' reading achievement, (b) enhances teachers’ ability to teach effectively, and (c) is more effective than other types of professional development. (Remember, having elements that are supported by research doesn’t make the program research-based. Every program has some element that can be supported by research.)
