Discussion¶

Of Barton's 81 eighth-grade graduates of 1993, 44 graduated within five years, 26 dropped out, and 10 left CPS — a broader claim this one bears on
Five-year graduation and dropout outcomes varied by eighth-grade ITBS achievement level, with students more than a year below grade level graduating at lower rates — a broader claim this one bears on
Among Barton's class of 1993, more girls than boys graduated within five years (25 of 46 versus 19 of 35) — related
