Validating Kohler's taxonomy of transition programming 2.0 for youth students with disabilities in the Saudi Arabian context.
The Arabic KTTP 2.0 is ready—use it to measure and fix transition services for Saudi students with disabilities.
01Research in Context
What this study did
Alqahtani et al. (2026) translated Kohler’s Transition Taxonomy into Arabic. They wanted a tool Saudi schools could use to check if their transition programs really work.
They ran a confirmatory factor analysis on the Arabic KTTP 2.0. The study looked at five areas: student-focused planning, student development, family involvement, program structure, and inter-agency teamwork.
What they found
The 132-item Arabic KTTP 2.0 held together. All five factors were strong and reliable.
Schools now have a clear, research-backed checklist to rate their transition services for students with disabilities.
How this fits with other research
Hong et al. (2021) also validated Arabic caregiver scales in Saudi Arabia. Both papers used the same factor-checking method and got positive results.
Almalki et al. (2021) paints a darker picture. Teachers in that survey said parents are rarely invited to transition meetings. The new KTTP 2.0 gives schools a way to measure family involvement, so the gap can be tracked and fixed.
Hume et al. (2018) in the USA showed students, parents, and teachers often disagree on transition skills. The KTTP 2.0 includes all three voices, so Saudi teams can spot and close those same disagreements.
Why it matters
You now have a free, Arabic, research-backed rubric. Use it to score your school’s transition program each term. Low family-involvement score? Schedule parent nights and track the number. Low student-development score? Add self-advocacy lessons and re-rate. The tool turns soft goals into hard data you can show administrators and funders.

03Original abstract
Improving post-school outcomes for youth with disabilities requires coordinated, evidence-based transition programming grounded in culturally valid measurement frameworks. This study culturally adapted and psychometrically validated the Saudi Arabic version of the Taxonomy for Transition Programming 2.0 (KTTP 2.0) for application in Saudi special education settings. Employing a multi-phase cross-cultural adaptation design, the instrument underwent forward-back translation, expert content validation (11 experts), and cognitive interviews with five teachers, resulting in refinement from 163 to 132 items. The final version was administered to 172 special education teachers delivering transition services to students with disabilities. Confirmatory factor analyses were conducted using theory-driven, domain-representative parcels. Models were estimated in R (lavaan) with robust maximum likelihood (MLR) and full-information maximum likelihood to manage the small proportion of missing data. A correlated five-factor first-order model demonstrated good fit, χ²(67) = 117.87, CFI = .969, TLI = .958, RMSEA = .085, SRMR = .032, with strong standardized parcel loadings (λ =.77-.95). The second-order model also demonstrated good fit, χ²(72) = 128.18, CFI = .966, TLI = .956, RMSEA = .087, SRMR = .040, with robust higher-order loadings (λ =.887-.988). Reliability and convergent validity were supported (ω =.837-.948; CR =.843-.951; AVE =.634-.859), whereas discriminant validity was mixed, aligning with a coherent higher-order structure and substantial inter-domain covariance. Overall, the findings support the Arabic KTTP 2.0 as a reliable, structurally sound framework for transition program evaluation and improvement planning in Saudi Arabia.
