When ISTEP scores are released each year, buried in the rankings of the highest and lowest scoring schools is another story — schools that have made significant progress or seen precipitous drops.

In IPS, several traditional neighborhood schools made the top of the list. But many of the schools that saw the biggest gains in passing rates were innovation schools, which the district began creating two years ago. The schools are managed by outside charter operators or nonprofits, but they are still considered part of the district. The strong gains in passing rates are one of the first indications that the controversial strategy could pay off for the district.

Schools of every type show up on the list of campuses that saw the biggest declines in passing rates. But some schools on the list are particularly surprising because they have earned high marks from the state in the past.

These 10 schools had the biggest gains on ISTEP from 2016 to 2017

1. William McKinley School 39 — This neighborhood school in Fountain Square had the biggest jump in passing rates in the district. About 28 percent of students passed both the math and English tests, an increase of 9.7 percentage points over the prior year.
2. Cold Spring School — Formerly an environmental science magnet, this school converted to innovation status last year. Passing rates rose to 30.2 percent, up 8.7 percentage points.
3. Center for Inquiry at School 27 — An International Baccalaureate magnet school on the near north side, this school saw passing rates reach 33.8 percent, an increase of 8.4 percentage points.
4. Phalen Leadership Academy at School 93 — This innovation school on the far east side was taken over by the Project Restore team about three years ago. Last year, it became an innovation school in partnership with the PLA charter network. The passing rate at the school reached 38.2 percent, up 8.2 percentage points from the previous year.
