LA School Report on extended teaching days of Charter Schools yet where is their success?

At the top of the teaching days is Celerity Charter Schools, which ironically was raided by the FBI and found to be guilty of financial mismanagement. They eventually closed 2 schools. This chart was later removed by CCSA backed LA School Report

 (Celerity’s parent organization was raided by federal authorities earlier this year, following an investigation by LA Unified’s Office of Inspector General and reports by the district’s charter schools division concerning fraud, fiscal mismanagement and misuse of public money meant for schoolchildren. No federal charges have been filed, and a spokesman said Celerity remains unclear on what the federal investigation entails.) Ten of the 13 largest charter groups had more learning days on average, but three charter groups had fewer days of learning than other public schools in LA. They are:
Bright Star Schools
Synergy Academies
Magnolia Public Schools

The new report by the Stanford-based Center for Research on Education Outcomes (CREDO) on charter management organizations analyzed the academic progress of students in one academic year, studying 240 charter management organizations (CMOs) in 26 states, obtaining data from 3.7 million students.
