“…A number of studies have used instructional leadership about teacher academic optimism (Allen, 2011), school culture (Sahin, 2011), and school academic excellence (Alig-Mielcarek, 2003;Cheboi, 2016;McCoy, 2011;Sotarat et al, 2018), the teachers' performance (Hejres et al, 2017), the leader's performance (Harris, 2014;Issa, 2014), comparison of one school leader to another school leader (Staples, 2005). Other studies have used teachers' perceptions in order to evaluate their respective leaders, whether principal or assistant principal (Atkinson, Jr., 2013;Bada et al, 2020;DeVries, 2017;Finley, 2014;Gurley et al, 2016;Howard-Schwind, 2010) while one study analyzed the policies involved for instructional leadership (Chuta, 2018).…”
