The Leadership Practices Inventory (LPI) is a 30 item questionnaire containing five subscales for each of The Five Practices of Exemplary Leadership. Each subscale contains six questions, with a 10-point Likert response scale. The Leadership Practices Inventory exists in a “Self” and “Observer” version and takes approximately 10-20 minutes to complete.
In the Leadership Practices Inventory, Leaders complete the Self, rating themselves on the frequency with which they think they engage in each of the thirty behaviors. Five to ten other people—typically selected by the leaders—complete the Observer questionnaire, rating the leaders on the frequency with which they think they engage in each behavior. Respondents can indicate their relationship to the leader—manager, co-worker or peer, direct report, or other observer—but, with the exception of the leader’s manager, all the observers’ feedback is anonymous. The Leadership Practices Inventory is available in paper and online form.

Items in the LPI are highly correlated within each scale and test-retest reliability is high. Internal reliability, as measured by Cronbach’s Alpha, is strong, with all scales above the .75 level. Empirical tests of differences between leaders (using the Leadership Practices Inventory-Self form) and their constituents (using the Observer form) reveal no statistically significant differences (at the .001 level of probability) between these two groups on Challenging and Modeling. While statistically significant, the mean differences between these two groups on Inspiring, Enabling, and Encouraging have little practical significance, except to note that leaders view themselves as engaging slightly less in Inspiring and Encouraging, and slightly more in Enabling, than do their constituents.
A five-factor solution for the Leadership Practices Inventory (both the Self and Observer versions) was generated by a factor analysis, using principal component analysis with varimax rotation and Kaiser normalization. While some statements loaded on more than one factor, their highest loading was generally with the other statements conceptualized as comprising that factor (scale). These results provide continued empirical support for these various leadership behaviors to be conceptualized within five practices (challenging, inspiring, enabling, modeling, and encouraging).
Scores on the Leadership Practices Inventory relate significantly to other measures of leadership.
