Part eleven

The four-credit rule was the fix. The escape hatch was built in with it.

To understand what a mathematics credit means in North Carolina now, it helps to know why there are four of them.

Until 2009 the state did not have one graduation standard. Students chose among four courses of study. College and University Prep required four mathematics credits. Career Prep required three. College Technical Prep required three. The Occupational course of study required three. A student could finish a legitimate North Carolina diploma with three math credits and no reason to think anything was missing.

Then the University of North Carolina moved. In April 2000 the Board of Governors raised its minimum admission requirement to four mathematics courses, and the change reached students entering ninth grade in the autumn of 2002. The state's graduation requirements did not move with it. As the economists who later studied this period put it, high school graduation requirements in North Carolina “remained unchanged for 9th graders entering between 1999/00 and 2008/09.”

So for seven years the two standards were out of alignment, and nothing in the system was obliged to tell a student. You could meet every requirement your school set, walk across the stage, and find out at the application that you had never taken the fourth course. The mismatch was structural, and it fell on exactly the students whose families had nobody to check the fine print.

The State Board fixed the mismatch by making the college track the default. It adopted the Future-Ready Core in 2007. It applied to every ninth grader entering in the autumn of 2009, which made the Class of 2013 the first cohort to graduate under it. Four mathematics credits, for essentially everyone.

One chamber asked to look before they leapt

In March 2007 a bill was filed to slow this down. Senate Bill 1532 would have directed the Joint Legislative Education Oversight Committee to study the new requirements and “any unintended consequences that may arise as a result of the implementation.” Its operative sentence was unusually blunt: “The State Board of Education shall not implement the Core Course of Study until the Committee completes its study.”

The bill was reported favourably in April, withdrawn from the calendar twice, and re-referred to committee in May 2007. It never became law, and the study was never done. The following January a state senator put the worry plainly in a hearing: “It would serve no useful purpose to raise the requirements and then push more kids into failure and dropout.”

Then the requirement met the classroom

Federal researchers later pulled North Carolina transcript data to count how often students repeated a course after failing it. The years line up with the first Future-Ready cohort moving through.

H., Stanhope, D., Starcke, M. and Li, D., Academic outcomes for North Carolina Virtual Public School credit recovery students, REL 2017-177, Regional Educational Laboratory Southeast, Institute of Education Sciences, Table 2. These are course enrolments in credit recovery, not distinct students, and they cover only face-to-face repetition after a no-credit first attempt; third-party online providers could not be separated out. The report draws no causal conclusion, and neither do we.

Read it carefully, because the honest version is more interesting than the simple one. Summer school repetition of Algebra II nearly tripled, from 436 to 1,194. School-year repetition of Geometry rose 83%, from 4,372 to 7,994. But school-year Algebra II repetition did not climb steadily; it fell from 5,101 to 3,458 and then jumped to 5,879, ending only 15% above where it started. The spike is real and it is concentrated in 2011‑12, the year the Class of 2013 was in eleventh grade. That is chronology, not proof.

And here is the part that changes the story. The obvious narrative is that the state raised the bar, discovered it could not deliver, and invented the credit substitutions as a way out. That is not what happened. A Department of Public Instruction mathematics options chart revised 5 November 2010, before the repetition spike appears in the data at all, already splits the fourth math course into two panels: “Courses that are accepted by the UNC General Administration” and “Courses that are not accepted by the UNC General Administration but may be suitable for meeting the ‘4th Math’ for high school graduation.” Under the second panel, a column headed “CTE Courses that are acceptable substitutions” lists Computerized Accounting II, Drafting II, AP Computer Science, Principles of Technology I, Electronics I, and seven engineering courses. The escape hatch was not a workaround bolted on after a crisis. It was designed in from the beginning, and the state has been explicit the whole time that walking through it means not qualifying for the state's own universities.

Which leaves North Carolina saying, accurately and continuously since 2009, that it requires four mathematics credits to graduate. What that sentence buys a student has been a separate question from the start.
