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 with harmonization · moderate confidence
No blocking method discontinuity is identified inside the selected cycle span, but one or more longitudinal changes require explicit harmonization conditions before pooling.
Evidence provenance: Praxis automated inference from indexed CDC/NCHS evidence
Relevant boundaries: 2005-2006 → 2007-2008 · 2007-2008 → 2009-2010 · 2009-2010 → 2011-2012 · 2011-2012 → 2013-2014 · 2013-2014 → 2015-2016
Praxis harmonization actions
- Verify merge grain, companion variables, and component-specific analytic guidance for the new file context.
- Apply cycle-specific eligibility rules and restrict the pooled analytic population to a defensible common target population.
