Remember, the purpose of this tool is to help you explore and assess how you embody the three virtues of an ideal team player. The standards for 'ideal' are high. An ideal team player will have few of these statements answered with anything lower than a '3' (usually) response.
A score of 18 or 17 is an indication that the virtue is a potential strength.
A score of 16 to 14 is an indication that you most likely have some work to do around that virtue to become an ideal team player.
A score of 13 or lower is an indication that you need improvement around that virtue to become an ideal team player.
Finally, keep in mind that while this tool is quantitative, the real value will be found in the qualitative, developmental conversations among team members and their managers. Don't focus on the numbers, but rather the concepts and the individual statements where you scored low.
