How does Iowa calculate its graduation rate?

Answer: 

Iowa started reporting a cohort graduation rate starting with the Classes of 2010. This method of calculating rates is consistent with the of the National Governors Association cohort graduation rate. The form is as follows:

Four Year Cohort Graduation Rate for Class 2012 = (FG + TIG) / (F + TI - TO)

FG = First time 9th grade students in fall of 2008 and graduated in 2012 or before.

TIG = Students who transferred in the cohort in grades 9 to 12 and graduate in 2012 or before.

F = First time 9th grade student in fall of 2008.

TI = Transferred into the first time 9th graders' cohort in grades 9 to 12. TO = Transfer out (including deceased).

 

Five Year Cohort Graduation Rate for Class of 2011= (FG + TIG) / (F + TI - TO)

FG = First time 9th grade students in fall of 2007 and graduated in 2012 or before.

TIG = Students who transferred into the cohort in grades 9 to 12 and graduate in 2011 or before.

F = First-time 9th grade student in fall of 2007.

TI = Transferred into the first time 9th graders' cohort in grades 9 to 12. TO = Transfer out (including deceased).
