Most research indicates that effective principals usually involve teachers in some of the decision-making processes that take place in a school. When teachers feel they have a voice in decisions, they are more likely to take ownership in their school. Great leaders have the power to change their school either for the advancement of the establishment, or they can bring about negativity in the workplace. The purpose of this study was to determine if there were differences on the 5 dimensions of the Kouzes-Posner Leadership Practices Inventory (Model the Way, Inspire a Shared Vision, Challenge the Process, Enable Others to Act, and Encourage the Heart) between teachers’ scores and their principal’s score for participants in this study, and to determine if a relationship existed between teachers’ scores on the Purdue Teacher Opinionaire and their principal’s Leadership Practices Inventory score. For this research data were collected from 10 schools in a school system in East Tennessee that contained kindergarten through eighth grade. These schools are classified in 3 categories: kindergarten through eighth grade, third through fifth grade, or sixth through eighth grade. There were 208 participating teachers in the school system who teach kindergarten through eighth grade. One-sample t-tests were used to compare the principal’s Leadership Practice Inventory score to teachers’ Leadership Practice Inventory scores at each of the 10 participating schools. Scores for teachers and their principal were not significantly different for any of the 5 dimensions for Schools 1, 2, 9, and 10. School 8 displayed a significant difference for 3 of the 5 dimensions. The means were significantly different for Schools 3, 4, 5, 6, and 7 on all 5 of the dimensions. The relationship as measured by Pearson correlation coefficients between the Leadership Practices Inventory and the Purdue Teacher Opinionaire for teachers at the 10 participating schools displayed similar mixed results.

This study investigated the level of leadership practices and retention rates of freshman students at Texas Woman's University. The data for the study were collected using the Leadership Practices Inventory, Student Version. The sample for the study consisted of 151 freshman students. The students were each placed in one of three control groups. Group A students (the treatment group) were in the Neighbors Educated Together Program (NET). Group B students (control group) were in one of two university-sponsored programs (COLORS or University 1000), and Group C students (control group) were the residual group of first-time college freshmen. These three groups were surveyed prior to their participation in the NET program or a university-sponsored program and again at the end of 14 weeks. In addition, retention rates were examined on the 12 class day of the spring semester. The study found statistically significant differences (p <. 05) on the pretests and posttests between Group C, residual students, and the other two groups on the Enabling the Followers to Act subscale, the Inspiring a Shared Vision subscale, and Encouraging the Heart subscale. Group A, NET students, and Group B, COLORS/University 1000 students, showed no statistically significant differences between groups. The difference from the residual group could indicate that students who self-select into programs such as NET, COLORS, and University 1000 are more likely to engage in practices measured by the subscale prior to enrollment in the respective programs. No statistically significant differences were found on the Challenging the Process or Modeling the Way subscales. The lack of significance shows that there are no differences in practices for any of these groups prior to enrollment at the university or as a result of participation in a university-sponsored program such as NET, COLORS, or University 1000. A chi-square test was performed following the 12 class day for the Spring 2001 th semester. Approximately 89% of the students in Group C Residual, 97% of Group B COLORS/University 1000, and 91% of Group A NET were retained. The chi- square frequency test revealed no statistically significant differences in level of retention between groups.

Some research suggests that development of professional learning communities might be the organizational strategy that could make school reform more successful. While most schools have not institutionalized the essential components of learning organizations, studies have demonstrated that these attributes must be developed if professional staffs are to realize the full benefit of organizational learning and in the process, create a context of improvement. The primary intent of this study was to learn and understand how principal behaviors influenced the development of shared leadership, shared vision, and supportive conditions; three essential dimensions of professional learning communities. Secondly, this study investigated how these conditions differed among schools which have and have not sustained high levels of student learning. Understanding the influence of principal leadership on conditions for organizational learning can be partially understood through either quantitative or qualitative methods. From this perspective, the mixed methods design utilized in this study allowed both qualitative and quantitative data to be analyzed and interpreted as evidence in understanding the study's problem. Principal and teacher focus-group interviews were used to create a deeper understanding of how principals worked to create conditions for organizational learning. Kouzes and Posner's (2002) Leadership Practices Inventory - Self and Observer Forms were utilized to identify, describe, and measure the perceived leadership practices of principals. The findings of this investigation suggest that principal leadership is a key factor in creating conditions for organizational learning and sustaining high levels of student achievement. Principals in this study who effectively identified and modeled espoused values were perceived to be highly visionary and appeared more effective at sharing leadership, inspiring vision, and creating supportive conditions. Principals who were able to develop a shared vision among staff created strong collaborative cultures characterized by an uncompromised focus on student learning. The findings of this study also indicated that principals who effectively Model the Way, Inspire a Shared Vision, and Enable Others to Act, distributed leadership among staff and demonstrated a systems orientation to leading.

This study, one of four cohort studies, was designed to determine the relationship between student performance and leadership practices as perceived by principals and selected site-based decision making committee members of middle schools in the Region 5 Education Service Center area of Texas. Using the Leadership Practices Inventory developed by Kouzes and Posner, the study compared the perceptions of middle school principals and selected observers regarding leadership practices. These leadership ratings were compared to student achievement for each campus in the study. In addition, the study examined if selected demographic variables impact the perception of leaders and observers in regard to leadership. For schools in this particular study, there was no direct correlation between perceived leadership practices of the principals and student achievement as measured by the Texas Assessment of Knowledge and Skills (TAKS) tests. This was true of total LPI scores and also of each individual practice measured by the LPI. The data revealed that principals in the study rated themselves higher as a group than their observers rated them on the LPI. This trend was consistent for the total instrument and for each leadership practice. There were also similarities, however, between the two groups. The practice Model the Way had the highest mean for both groups, while Inspire a Shared Vision and Enable Others to Act were rated lower by both groups of respondents. A researcher-developed questionnaire was used to gather demographic information about each respondent. Years of experience, age group, gender, and ethnicity were all studied to determine if they had any effect on responses. The results indicate that there were some differences when principals and observers were studied separately, but these differences were minimized when the two groups were combined. Of particular interest was the fact that younger principals and less experienced principals rated themselves more conservatively than their older and more experienced colleagues. Younger observers and less experienced observers, however, had a propensity to rate their leader high when compared to older observers and more experienced observers. Neither ethnicity nor gender had an impact on leader ratings.

The purpose of this study was to determine if the teachers in Sullivan County perceive that principals used the same leadership practices as the principals reported they use. The researcher used the survey method of data collection in which 897 teachers were given the opportunity to participate and 576 teachers returned completed surveys (63.2%). In addition, 29 out of 29 principals participated in the research (100%). The Leadership Practices Inventory (LPI) (Kouzes & Posner, 2003a) was used to gather information regarding the principals' leadership practices. Principals self-reported their perception of their leadership practices, whereas teachers reported their perceptions of their principals' leadership practices. Two major findings of this study were that principals reported significantly higher levels of each leadership practice than both the Kouzes-Posner norms and their teachers' perceptions of their principals' leadership practices. In addition, there was no difference between male and female teachers' perceptions of their male principals' leadership practices. However, there were significant differences between male and female teachers' perceptions of their female principals' leadership practices for all five behaviors. In each case, male teachers evaluated their female principals' leadership practices higher than did female teachers.

The purpose of this study was to compare the perceptions of self-reported leadership practices using the Kouzes and Posner Leadership Practices Inventory between high school principals in North Carolina who were coaches with those principals who were not coaches. This quantitative study was conducted using a survey-design method in which all 368 public high school principals in North Carolina were given the opportunity to participate. A Principal Demographic sheet along with the 2003 edition of Kouzes and Posner's Leadership Practices Inventory (LPI) Self- Form was used to gather information regarding the principals' perceptions of their leadership practices. The response rate was 64.9%. This study determined that for the research question: Do the Kouzes and Posner mean scores (for the five dimensions) differ between principals who have been coaches and those who have not, no significant difference, as measured by η2 (< .01) was reported in any of the five dimensions. This study established that North Carolina high school principals reported significantly higher levels on each of the 5 leadership practices than did those individuals in the Kouzes and Posner study. In addition, a positive relationship was found between the number of previous years of coaching experience and 3 of the 5 leadership practices. The study determined that there was little difference in the mean scores between male and female North Carolina principals.

The purpose of this study was to examine the relationship between Tennessee wardens’ leadership practices and correctional officer job satisfaction. Utilizing the Leadership Practices Inventory (LPI), the relationship between correctional officers’ perception of the warden’s leadership practices and the LPI norms were examined. Additionally, utilizing the LPI, the relationship between self-ratings of the warden’s leadership practices and the observer rating of the LPI were assessed. Lastly, utilizing the Job Satisfaction Survey (JSS) and observer LPI, correlations were examined between the correctional officers’ job satisfaction and their perception of the warden’s leadership practices. Findings of this study showed lower correctional officers ratings of the wardens on the five LPI subscales than the inventory’s norms. In a comparison of the LPI wardens’ self-perception and the correctional officers’ observer perception, correctional officers rated the wardens lower than the wardens rated themselves. The overall ratings of the correctional officer Job Satisfaction Survey (JSS)were neutral. However, of the nine JSS subscales, the results identified the nature of their work and supervision as the most positive. Pay, contingent reward, and promotional opportunities were rated as the primary reasons for job dissatisfaction. Additional findings indicated a positive relationship between job satisfaction and each of the five subscales of the LPI. / Doctor of Philosophy in Leadership

The purpose of this research project was to examine whether frontline nurse managers who had attended a leadership program, perceived their leadership style as containing behaviors representative of transformational leadership. A secondary purpose was to determine the participant's opinions about the value of a leadership program for their practice. Current literature was utilized to support this research project examining a nursing systems issue.The primary instrument used to collect data about leader practice was the Leadership Practices Inventory (LPI) (University of Georgia, 2002). An evaluation tool was also designed and utilized to gather information about the participant's perception of their leadership behaviors after completion of a training program. Survey participants were selected from nurses who completed the Arizona Healthcare Leadership Academy (AzHCLA) (2007) course in the last four years.A course survey and results from the LPI revealed that study participants perceived an increase in their behaviors related to leading others as well as having learned new skills by having completed the AzHCLA course. Nurse's educational levels were compared to the five leadership practice subgroups from the LPI to examine whether a nurse's educational level could better account for an increase in leadership competencies. Research data revealed that no relationship between educational levels existed but that certain leadership skills were gained by having completed a leadership educational program. By using descriptive statistics, mean scores were used to identify differences in how nurses perceived their individual competencies and behaviors after having completed leadership education. Reported perceptions of competencies and behaviors indicated that educational programs can be beneficial to frontline nurse leaders.While results from an ANOVA showed there was no statistical significance related to education and LPI subgroups, there was a trend in the mean differences for those individuals with a master's degree. Qualitative data revealed that course participants perceived having gained new leadership skills and behaviors. The data from this study created a baseline of information that warrants further investigation to identify if indeed education makes a difference in perceived leadership practices.

The purpose of this research was to investigate the relationship between leaders’ self-awareness and their effectiveness. The population included leaders with at least five years of experience in a leadership role. Participants were recruited by snowball sampling methods; the researcher used a diverse network of professionals to recruit other leaders from diverse industries. Each leader completed a 35-survey questionnaire along with demographic questions (gender, education, years in leadership role, industry), and was required to ask at least four direct reports to complete the 35 questions about observed behaviors of their leader. After removing incomplete responses, the final sample included N = 179 leaders, each with at least four direct reports (N = 761). Data were collected using three well-established, validated research instruments for this quantitative correlational study: the Emotional and Social Competency Inventory (ESCI) (Boyatzis, 2007), the Leadership Practices Inventory SELF (LPI-SELF) (Kouzes & Posner, 2013b) and the Leadership Practices Inventory OBSERVER (LPI-OBSERVER) (Kouzes & Posner, 2013a). LPI surveys provided five independent leadership competency scores: Modeling the Way, Inspiring a Shared Vision, Challenging the Process, Enabling Others to Act, and Encouraging the Heart (Kouzes & Posner, 2012). Qualtrics, an approved third-party online survey platform, was used to collect and analyze study questions. The study measured direction and strength of leaders’ LPI scores and self-awareness, the direction and strength of how the direct reports’ rated their leaders’ LPI practices and the leaders’ self-awareness; it also measured if there were significant differences in how the leaders rated themselves based on gender, education and time in a leadership position. The results indicated a positive, but not strong relationship between leaders’ own LPI scores and self-awareness. The relationship of the direct reports’ observation of leaders and their self-awareness appeared positive and strong for each of the five competencies. The correlation of the five LPI-SELF competencies and self-awareness to gender did not appear significantly different. Results appeared different in four of the five leadership practices based on education. Only Challenging the Process was similar for all educational levels. Whereas, years as a leader appear similar in four of the five leadership practices, and only Modeling the Way showed different results.
