This on-line personality inventory is not optimized for tablets or phones. A device with a full-sized screen is not necessary, but recommended.
When you finish the inventory and your narrative report is displayed, YOU are responsible for saving the report before you leave that Web page, using the instructions at the top of the report. Individual reports are NOT saved by the system, so if you close the report Web page, you will not be able to return to your report.
Purpose and Limitations of the IPIP-NEO On-Line Personality Inventory
More specifically, the report explains the likely consequences of one's
standing on five broad personality domains.
These broad domains cover normal differences in personality that should
be obvious to people who know you well.
Secondarily, this inventory estimates your standing on the 5 broad domains
and 30 subdomains of personality.
The inventory does not reveal hidden, secret information about you nor
does it assess serious psychological disorders.
The report is designed to be objective, not pleasing or flattering.
Measurement error, misunderstandings, carelessness, too many missing responses, and mischievous responding
can invalidate the report.
If knowledgeable acquaintances disagree with the test results, they are most likely correct and the test results are wrong.
On rare occasions, responding to all of the items will fail to produce a report. In such cases a problem with your Internet connection or with the server for this site is probably at fault. If a crash occurs, results are not saved and you must start the inventory from the beginning. Your best bet for completing the inventory is to simply wait an hour or two and try again. You may want to use a different machine and/or Internet connection. If you experience any technical difficulties (items fail to appear on the screen, test does not advance to next page, Web browser freezes, no narrative report is displayed, etc.) you may send an email describing the problem to me at email@example.com, although it is unlikely that I can provide help beyond the suggestions in this paragraph.

The IPIP-NEO is not equivalent to the commercial inventory
on which it is based, the NEO PI-Rô, authored by Paul T. Costa, Jr. and
Robert R. McCrae. The genuine NEO PI-Rô (240 items) is considered by many
psychologists to be the best inventory for measuring traits within the
Five Factor Model (FFM) of personality. The NEO PI-Rô is copyrighted by
Psychological Assessment Resources (PAR) in Florida, and can only be ordered
by professionals and used by permission. You can contact PAR at: 1-800-331-TEST,
The development and validation of the IPIP-NEO is described in the following publication:
