Oklahoma, CSTA, and Texas Computer Science Standards Side by Side: A Three-Way Crosswalk
Oklahoma, CSTA, and Texas Computer Science Standards Side by Side: A Three-Way Crosswalk
Teachers and curriculum leads keep asking the same question: if Oklahoma and Texas both teach computer science, how much of it overlaps? We compared every Oklahoma OAS-CS unit and every Texas TEKS point with the national CSTA K-12 standards (2017 edition), one by one, and then joined the results through CSTA. This post summarizes what that three-way crosswalk shows.
Edition note: this comparison uses the 2017 CSTA K-12 Computer Science Standards, the edition Oklahoma and Texas standards align with today. CSTA published a revised PK-12 edition in 2026 with new standard codes. A 2026 version of this crosswalk is in progress.
How the three-way link works
CSTA is the bridge. When an Oklahoma unit and a Texas unit both map to the same CSTA code, they were each judged nearest to that standard. That is an inferred link, not a direct comparison of the two state standards, so treat each pairing as a starting point and check the standard text before relying on it for compliance or pacing.
The headline numbers
- 114 CSTA codes are used by at least one state’s units: 56 by both Oklahoma and Texas, 58 by Oklahoma only, and 0 by Texas only.
- Oklahoma: 216 of 225 units (96%) map to a CSTA standard. Oklahoma wrote OAS-CS as an adoption of the CSTA framework.
- Texas: 162 of 297 units (55%) map to a CSTA standard. 135 Texas units, covering topics such as keyboarding, ergonomics, and device-use rules, have no CSTA counterpart.
Grade by grade
“Shared codes” counts the CSTA standards that both states’ courses at that grade map to. The High School row pairs the Oklahoma Level 1 and Level 2 courses with Texas Fundamentals of Computer Science.
| Grade | OAS units | TEKS units | Shared CSTA codes | Note |
|---|---|---|---|---|
| K | 0 | 18 | 0 | No OAS-CS Kindergarten course |
| Gr 1 | 19 | 20 | 12 | |
| Gr 2 | 19 | 23 | 15 | |
| Gr 3 | 22 | 29 | 16 | |
| Gr 4 | 22 | 29 | 14 | |
| Gr 5 | 22 | 29 | 17 | |
| Gr 6 | 22 | 36 | 10 | |
| Gr 7 | 22 | 36 | 10 | |
| Gr 8 | 22 | 38 | 11 | |
| High School | 55 | 39 | 8 | OAS Level 1 + Level 2 vs. TEKS Fundamentals of CS |

Get something free every week
Each week I send one free resource for Oklahoma and Texas computer science teachers, such as a standards-at-a-glance sheet, a crosswalk, or a unit sample. When you join, reply with your grade level and the standard you find hardest to teach. I read every reply and use them to decide what I build next.

Fit ratings are judgments, and reasonable reviewers may differ, especially on partial and different-band matches. CSTA standards are cited by code only.
