However, Hoxby, Murarka, & Kang (2009) found that some policies of charter schools reforms had associations with better effects on achievement including a longer school year, more time devoted to English each day, a small rewards and small penalty discipline policy, teacher pay based somewhat on performance, and a mission statement that emphasizes academic performance. More than twenty years from 1980 to 2011, the Sweden studies reported the effects of the decentralization of authority and decision making over school budgets from central policy makers to the local municipalities and school principals, teachers and students in 35 schools. The Sweden students form these schools obtained in PISA maths and science scores fell by 48% and 42% respectively in that country (Blossing & Ekholm, 2008; Wilby, 2011). In the same direction, the meta-analysis led by Caldwell (2007, p. 30) in Australia and four international studies concluded that school-based management will deliver no impact on learning unless purposeful links are made at the student and classroom level. Some studies suggest the mixed method (qualitative and quantitative) and ethical consideration in evaluation process. Blossing & Ekholm, (2008) shown the qualitative indirect impact of this reform in Swedish companies about the significant education providers by free schools. The 23 state funded free schools are positioning itself to enter the UK market and take advantage of the opportunities of the emergence of free schools.
