Okla. Stat. tit. 70, § 70-3-151.1

index.

A. For purposes of establishing a uniform and accurate

definition of high school graduation rate for school districts and

secondary schools in this state, the State Board of Education shall

adopt and implement a four-year adjusted cohort graduation rate and

an extended-year adjusted cohort graduation rate. The Board shall

utilize and report the four-year adjusted cohort graduation rate and

the extended-year adjusted cohort graduation rate at the secondary

school site, the school district, and the state level, and the

graduation rates shall be reported in the aggregate as well as

disaggregated by subgroups as required in the Elementary and

Secondary Education Act of 1965 (ESEA) as reauthorized by P.L. No.

114-95, also known as the Every Student Succeeds Act (ESSA).

B. The Board shall use the four-year adjusted cohort graduation

rate for purposes of determining the high school graduation rate

indicator for the academic performance data calculation beginning

with state and district report cards providing results of

assessments administered in the 2011-2012 school year. The Board

shall use the four-year adjusted cohort graduation rate for

establishing the high school graduation rate for measuring alternate

year percentage growth targets as set forth in Section 3-151.2 of

this title beginning with the 2012-2013 school year.

C. The four-year adjusted cohort graduation rate shall be

defined as the number of students who graduate in four (4) years

with a standard high school diploma divided by the number of

students who entered high school four (4) years earlier. Students

who transfer out of the school or emigrate to another country and

deceased students shall not be included in the adjusted cohort

graduation rate. Twelfth-grade students who transfer into a school

after October 1 of any school year shall not be included in the

adjusted cohort graduation rate. Students who graduate in four (4)

years shall include students who earn a standard high school diploma

at the end of their fourth year, before the end of their fourth

year, and during a summer session immediately following their fourth

year. To remove a student from a cohort, a school district shall

confirm in writing or by electronic means that a student has

transferred out of the school site or school district, has emigrated

to another country, or is deceased. For a student who transfers out

of a school site or school district, the written or electronic

confirmation shall be official and document that the student has

enrolled in another school site or school district or in an

educational program that culminates in a high school diploma

recognized by a state or private higher educational institution

accredited or recognized by the Oklahoma State Regents for Higher

Education for purposes of admission to the institution. Students

who are not enrolled in a program which culminates in the award of a

credential recognized by a state or private higher educational

institution for purposes of admissions shall not be included in the

graduation rate calculation as set forth in this subsection as a

student who graduated in four (4) years with a standard high school

diploma but shall be included in the number of students who entered

high school four (4) years earlier.

D. The extended-year adjusted cohort graduation rate shall be

defined as the number of students who graduate in four (4) years or

five (5) years with a high school diploma divided by the number of

students who form the adjusted cohort for the four-year graduation

rate as calculated as provided for in subsection C of this section.

The extended-year adjusted cohort graduation rate shall be reported

separately from the four-year adjusted cohort graduation rate.
