YOUR HOLLAND CODE
This chart is "Holland" in one glance. That is to say, "John L. Holland" and his "Holland Code." Here are the six letters of his code, with a description of definitions, clues, typical activities, competencies, and occupations, for each. It is an expansion of the exercise found on page 129 in the current (2015) edition of What Color Is Your Parachute?
This wheel is entitled "Different Spokes for Different Folks", © 1976 by Jerry Hanisko and Lorraine Massaro. They handed it to me at an Iowa conference in 1977.
If you want to enlarge this wheel, above, so as to read the print more easily, there is a cute trick on a Macintosh keyboard for doing that: just press "Command" and the "+" key (upper right hand keyboard next to the delete key) at the same time. You can do this as many times as you need to. To reverse, just press "Command" and the minus key (right next to the "+" key) at the same time, as often as you want. So much for Macs. I'm sure other keyboards have a similar trick.
If you want a print copy of the enlarged wheel, that can be found on pages 426ff in my work, The Three Boxes of Life and How to Get Out of Them © 1981; out of print but still available at Amazon.com for around four bucks.
