How to do it

There are two types of card sorting: open and closed. Most card sorts are performed with one user at a time, but you can also do the exercise with groups of two to three people.

Open card sort

  1. Give users a collection of content represented on cards.
  2. Ask users to separate the cards into whatever categories make sense to them.
  3. Ask users to label those categories.
  4. Ask users to tell you why they grouped the cards and labeled the categories as they did.

Closed card sort

  1. Give users a collection of content represented on cards.
  2. Ask users to separate the cards into a list of categories you have predefined.
  3. Ask users to tell you why they assigned cards to the categories they did.

Considerations for use in government

No PRA implications. The PRA explicitly exempts direct observation and non-standardized conversation, 5 CFR 1320.3(h)3. It also explicitly excludes tests of knowledge or aptitude, 5 CFR 1320.3(h)7, which is essentially what a card sort tests (though in our case, a poor result is our fault).
