Confused about where to study planning? Of course there's the Planetizen guide but in the United States two free sources of information provide extensive lists of potential schools.
The Association of Collegiate Schools of Planning publishes The Guide to Graduate and Undergraduate Education in Urban and Regional Planning. The fifteenth issue came out on October 26 and is available for free download at http://www.acsp.org/education_guide/overview. This 368 page tome provides detailed, standardized information on each CASP member school: "FULL members are those giving planning degrees in the US. AFFILIATE members are generally those schools in the U.S. that give degrees related to planning but not planning degrees (urban studies or urban geography). Schools outside the U.S. are eligible for CORRESPONDING membership if they give planning or related degrees" (p viii).
The Planning Accreditation Board lists all credited planning programs including addresses and web sites: http://www.planningaccreditationboard.org/index.php?id=30. Most are in the United States.if planning is for you, find the right program, write a statement of purpose, apply, visit, and decide which offer to take up.
