The purpose of this study is to review the literature on the Teaching and Learning International Survey (TALIS) for the past 10 years to identify multiple paths through which school leadership exerted influences on school organizations and organizational outcomes. Our analysis of a network, consisting of 83 nodes (variables) and 242 variable ties from 29 reviewed studies identified four emergent themes. Reviewed studies (1) overwhelmingly framed the principal as the driver and teachers as the target of change; (2) suggested nine core variables (e.g., instructional leadership) to play central roles within the reviewed studies; (3) depicted student academic achievement as a function of the principal’s instructional leadership and their job satisfaction influenced by school context, principal qualification, and organizational conditions (e.g., respect for others); and (4) suggested teacher self-efficacy as the potential bridging variable between multiple change processes. The discussion includes implications for school leadership and future research.

Some secondary school principals are complaining about teachers’ reluctance to participate in any activities beyond classroom teaching. To understand this phenomenon, the study attempts to explore the inhibiting factors that hinder teachers in selected secondary schools in the Maseru district from supporting and engaging in teacher leadership (TL) activities. This qualitative inquiry is underpinned by the critical theory (CT), which among others aims at revealing the core factors that contributed to teachers’ lack of enthusiasm in performing various TL related activities. Also, to suggest strategies that could pioneer a change in teachers’ attitudes towards participation in school leadership beyond teaching. The study generated data from ten (10) purposively selected secondary school teachers. Using the thematic analysis method, despite participating teachers being able to conceptualise TL, they cited that, factors including; unmanageable teaching loads, inadequate induction, and use of top-down leadership approaches inhibited TL initiatives. To mitigate the abovementioned factors, participants suggested the creation of a supportive school environment, teacher training and recognition.

There is little empirical evidence that convinces the effectiveness of distributed leadership in contemporary educational research. Thus, many distinguished scholars suggest its’ statistical examination. Considering this need, the primary purpose of this study was to investigate the effects of principals’ distributed leadership practices on students’ learning outcomes at Technical and Vocational Education Training schools in Eritrea. The study was conducted based on quantitative design and applied structural equation modelling. A sample of six hundred and three students was employed. The researcher developed the structural equation model to test a model that hypothesized the relationship between the major variables using path analysis. The study results demonstrate that the principals’ distributed leadership practice has a direct and significant (.883, p<.001) effect on students’ learning outcomes keeping other things constant. The strongest predictor of students’ learning outcomes was capacity building, given it has the largest path coefficient (β=.346). Moreover, findings show gender disparity among the respondents and in terms of turnout rate; nevertheless, it was not statistically significant (p<.001). One of the study’s contributions is that it developed and assessed the validity of the principals’ distributed leadership practice scale for Eritrea’s TVET schools through CFA model. The study offered basic evidence that distributed type of leadership is a significant predictor of learning outcomes by exploring six factors of leadership practices, which shows a promising area for practice and future studies.

Organizationally, what does not get measured is not prioritized or improved. Unlike student outcomes, the leadership environment that produces the results is rarely examined for its merit and impact. In this study, a quantitative survey gathered information to investigate the impacts of leadership capacity constructs on academic achievement. Principals from 161 public high schools and their schools provided the data (leadership capacity, demographics, and reading and math scores). Data were analyzed using descriptive, correlational, and regression statistics. Findings indicated significant high correlations among leadership capacity variables, significant relationships between school demographics (total school enrollment, percentage of low-income students, average class size, and attendance) and reading and math scores, and non-significant correlations between leadership capacity and academic achievement. The study delineated specific leadership capacity behaviors within the constructs that predicted student academic achievement in math and reading. The study suggests increased capacity and practice of these leadership behaviors to improve work setting and student achievement.

The study investigated the potential role of human resources exemplified by leaders' psychological capital (PsyCap) as a resource that may cross over to team-member exchange (TMX), and bring about desired organizational outcomes. We suggest a model where TMX of senior management teams serves as a team resource mediating the relationship between leaders’ PsyCap and organizational outcomes, as represented by team innovation, organizational citizenship behavior (OCB), and employees’ job satisfaction. The study, carried out among 86 elementary and junior high schools, indicated a positive relationship between leaders’ PsyCap and TMX. In addition, we found a significant relationship between TMX and the three measures of organizational outcomes. Furthermore, TMX partially mediated the relationship between leaders’ PsyCap and the desired outcomes, excepting innovation. The findings provide support for the importance of the leaders’ personal resource of psychological capital as a complementary perspective that may enhance our understanding of leadership’s impact on organizational success. In addition, the study provides significant support for the expanded model, broadening the definition of the crossover model by examining the translation of positive resources from leaders' PsyCap to organizational outcomes via teams' positive resources. From a practical perspective, the findings bring to the forefront the importance of psychological capital as a state-like construct that can be developed through leader preparation and professional development programs.
