This certificate focuses on building skills for natal chart interpretation. The required courses provide students with the skills they need to successfully interpret a natal chart, an understanding of many of the types of tools they can use (and any controversies surrounding them) and a consideration of the ethical issues involved. It gives students a broad enough view that they can also understand the different approaches available for interpretation (such as traditional, modern, or evolutionary) so they can decide for themselves what direction interests them further.

The standard certificate (30 weeks) requires W101, W102, and W103. The extended certificate (40 weeks of instruction) requires the natal chart practicum, W104, which hones student's ability to work with common client questions (based on actual client charts and issues).
