The U.S. Merit Systems Protections Board (MSPB) puts out a great newsletter focused on staffing called Issues of Merit.
The July 2007 edition has some great stuff in it, including:
- Risks inherent with using self-assessment for high-stakes decisions, such as hiring (hint: people are horrible at it)
- Tips for workforce planning
- How to write good questions
- Analyzing entry hires into the federal workforce
- An introduction to work sample tests
