CIP 2020, six years in: the codes nobody claimed, and the field that ran away with it

Every CIP revision drops hundreds of new codes into the taxonomy, and for years nobody has been able to say what happens next. Do colleges adopt them? Do the codes sit empty? Is a new series a genuinely new field, or old content renumbered? The 2020 edition has now been in force for six award years, 2019-20 through 2024-25, which is long enough to answer all three questions with data instead of anecdotes. We pulled the full 2020 edition from NCES, classified every new code, and matched the whole set against IPEDS Completions. The short version: most new codes got claimed, a handful never were, one field absorbed half the volume, and 39 of the 81 new series were never open for business at all.

The 2020 edition lists 2,848 codes. Against the 2010 edition, 1,994 carried no substantive changes, 149 moved, 12 were deleted, and 544 were new: 3 two-digit series, 81 four-digit series, and 460 six-digit codes. But the 81 new four-digit series split in a way nobody advertises. Thirty-two of them sit in the 60 and 61 series, medical residency and fellowship programs, whose own definitions state they are not valid for IPEDS reporting. Seven are Reserved codes. We verified both facts empirically: the 60 and 61 families have zero rows in the completions warehouse in any year. That leaves 42 new four-digit series that were actually open for business. When someone says the 2020 revision created "nearly 70 new four-digit series," the honest working number for anything completions-related is 42.

Colleges adopted the new series steadily rather than instantly. Awards conferred under the 42 new series, first majors only:

That is a tripling in six years, but it is a tripling of a small base: 56,101 of the 5,701,913 awards conferred in 2024-25, just under one percent of all credentials. New taxonomy is where growth shows up first, but six years in it is still a rounding error in national completions.

The most important split is between series that are genuinely new fields and series that are old content renumbered. Inside the 42 reportable new series, the 2020 edition files 72 new six-digit codes and 10 moved six-digit codes. The moved codes inherited existing programs on day one; the new codes had to be adopted program by program. The data shows the difference plainly. Cumulatively, moved children account for 105,484 awards and new children 99,246: renumbered content still leads over six years. But in 2024-25 alone the order has flipped, 37,097 awards through new codes against 19,004 through moved codes. Two-thirds of current new-series volume now flows through programs that did not exist under the 2010 taxonomy.

Of the 42 reportable new series, 38 have been claimed by at least one institution at some point in six years. Four never were, not once, not a single reported completer: 16.18 Armenian Languages, Literatures, and Linguistics; 30.50 Mathematics and Atmospheric/Oceanic Science; 32.02 General Exam Preparation and Test-Taking Skills; and 36.02 Noncommercial Vehicle Operation. And one series deserves its own line: 30.45, History and Language/Literature, was claimed by an institution, produced 356 awards in 2019-20, went to zero, produced 3 awards two years later, jumped back to 317 in 2023-24, and returned to zero in 2024-25. That is the full life cycle of a taxonomy experiment in six numbers.

Strip the renumbered neighborhoods out and one field dominates what is left. The two data science series together went from 874 awards in 2019-20 to 27,969 in 2024-25, a 32-fold ramp, and now carry 49.9 percent of all new-series awards. Inside them, the biggest new six-digit codes in the entire revision are Business Analytics (30.7102, 11,181 awards at 253 institutions), Data Science, General (30.7001, 11,020 at 384), Data Analytics, General (30.7101, 2,672), and Financial Analytics (30.7104, 2,582). The next tier of genuinely new content is a list of the decade's curriculum anxieties: Cloud Computing (11.0902, 1,612), Cybersecurity Defense Strategy and Policy (43.0404, 1,710), Digital Marketing (52.1404, 1,960), Mechatronics, Robotics, and Automation (15.0407, 997), Human-Centered Technology Design (11.0105, 998). The taxonomy follows the market with about a three-year lag, and the market of the late 2010s was analytics.

At the six-digit level the revision added 226 codes that are reportable in IPEDS, once the residency family is set aside. The adoption rate looks healthy at first glance: 199 of them have reported at least one completer in six years, and 194 reported in 2024-25 alone, so most new codes do get used eventually. But the distribution is brutally top-heavy. Thirty-one codes have produced fewer than 10 completions ever, collectively 84 awards. Fifty-eight more sit between 10 and 99. At the other end, 25 codes have produced 1,000-plus awards each, carrying 141,741 of the 173,857 cumulative new-code awards, 82 percent of the volume in 11 percent of the codes. A new CIP code is a lottery ticket with a decent floor and a power-law payout.

We downloaded the complete 2020 edition and the 2010-to-2020 crosswalk from the NCES CIP user site, classified all 544 new codes by action, level, and reportability (the 60/61 residency family and Reserved codes were excluded after verifying the 60/61 family has zero IPEDS rows ever), and matched the resulting lists against IPEDS Completions, first majors, the 2019-20 through 2024-25 award years. The counts and percentages in this post come from those queries; the full query log, the row sets, and both NCES source files are in the evidence folder for this post. One measurement caveat: the warehouse holds codes as institutions filed them each year, which is exactly what makes adoption measurable, but it also means pre-2020 years cannot be compared at the new-code level.

The taxonomy itself is covered in what is a CIP code, and the repair work for trends that cross the 2020 seam is in CIP 2010 to 2020: what moved and how to rebase your trends. To see what a claimed code looks like in production, the data science program page ranks every institution awarding credentials under the 30.70 and 30.71 series.
