Double Education

Last I saw there were 24 accredited undergraduate programs as compared to far more graduate programs. When researching graduate schools in planning I discovered a duplication of planning eduaction regarding urban history, statistics, land use, planning law, site planning, etc Out of the 12 schools I researched only one accommodated accredited undergards while other schools required non-measurable or defined standards. Thus is graduate school in planning worthwhile for undergrads from accredited programs or shall they seek related professions?
