Open call for proposals regarding website contributions

Open call for proposals regarding website contributions

On the occasion of the 80th anniversary of Psychometrika and 81th anniversary of the Psychometric Society, the Psychometric Society launches an open call to its members (senior or junior) to send in a proposal outlining a contribution in recognition of the anniversaries of the journal and the Society. If approved, such a contribution will become part of the Society’s website. Valuable contributions may be related to the history of the Society or its journal or they may help disseminating important psychometric contributions (this is a non-exhaustive list).

If you have an idea, please send in a 3-page proposal describing your idea, a timeline, a budget and a list of deliverables. The Society has reserved a total of $10000 that may be (partially or completely) used to fund at most two selected proposals. The deadline for submitting a proposal is April 1. Please send your proposal to Francis Tuerlinckx ( The proposals will be reviewed by the Board of Trustees. 

(Who is the man in the picture? If you do not know the answer, you should explore the history pages referred to above. Albert K. Kurtz was one of the six co-founders of the society. In fact, the society was his idea. He was founding editor of Psychometrika, together with Paul Horst, and has been the longest-serving editor of Psychometrika.)
