Scientific safeguard
Qualified assessment is authoritative; chronology remains supporting evidence.
Praxis separates source-stated method or instrument changes from automated differences in CDC/NCHS method text. The qualified harmonization assessment below is the researcher-facing conclusion; method chronology explains the underlying evidence and does not override that adjudication.
Variable-by-variable chronology
Qualified harmonization assessment and indexed evidence
Each variable first shows the current qualified assessment used by Study Builder, followed by cycle-specific source evidence and method chronology.

Qualified Praxis harmonization assessment
Compatible · high confidence
RIDRETH3 was introduced in 2011-2012 as an expanded race/Hispanic-origin recode that distinguishes Non-Hispanic Asian participants following the revised NHANES sampling design. It is a stable construct within its released era, but it is not simply a renamed RIDRETH1.
Evidence provenance: CDC/NCHS source-confirmed evidence · Praxis deterministic adjudication
Praxis harmonization actions
- Pool RIDRETH3 within 2011-2012 and later calibrated cycles when the expanded categories are analytically appropriate. Treat RIDRETH1 and RIDRETH3 as parallel construct variants; use an explicit common recode when combining analyses across their differing category schemes.
