This mixed-methods study identified the effective practices of the principal and leadership team in an Improvement-Required (IR) high school that significantly influenced student achievement and guided their school from IR to a rating of Met Standard in one year. IR or F schools under the new system are schools that failed to meet the state accountability target goals. The high school in this study had a large culturally and economically diverse student population with a high percentage of English learners. The leadership practices were identified through four themes revealed by the qualitative data analysis of focus group and individual in-depth interviews: (a) importance of instructional, collaborative leadership, (b) intentional planning of effective instruction for all students, (c) consistent use of data to guide instruction, and (d) ongoing, data based, targeted staff development. The study findings are significant due to strong corroboration between the qualitative data collected from the interviews and the quantitative results from the faculty survey.

The Nigerian banking industry has recently witnessed a major scandal resulting from financial impropriety of some corporate leaders in the industry. The Central Bank of Nigeria (CBN) invested the sum of N620 billion ($4.1 billion) as part of a direct bailout package to 8 banks, and removed top executives of those banks for gross leadership ineptitude. The leadership ineptitude is an indication of the need to better understand effective leadership practices in the Nigerian banking industry. Grounded in transformational leadership theory, the purpose of this multiple case study was to explore bank leaders' effective leadership practices used to sustain bank growth in Nigeria beyond 5 years. Data were collected from semistructured interviews with 5 Nigerian bank CEOs, direct observation, and document reviews. During thematic analysis, 4 themes emerged including establishing a direction, inspiring and motivating employees, raising other leaders, and developing and using leadership competence. The implications for positive social change include the potential for bank leaders to identify sustainable leadership practices, improve profitability, create more job opportunities, and ease unemployment problems in the community.
