The phrase "a valid change" is correct and usable in written English.
It can be used when discussing modifications or alterations that are acceptable or legitimate within a certain context.
Example: "After reviewing the proposal, we concluded that a valid change was necessary to improve the project's outcome."
Alternatives: "an acceptable modification" or "a legitimate alteration".
We investigated whether our new test can provide fair measurement and constitutes a valid change measure by testing the fit of one uniform Rasch model both on data from different groups of test takers (e.g., female and male students) and on pre- and posttest data (see, e.g., Bond and Fox, 2007; Hambleton and Jones, 1993; Lord, 1980).
Of the 1,797 transfers, 79percentt were a valid change of residence.

Others want to hold off doing anything after transfer statistics indicated a reduction following implementation of a new policy that began on Jan . 1 requiring those who make a valid change of residence to submit seven specific paperwork forms to schools to prove the move.
Instead of choosing a pre-determined threshold for determining the biological relevance of changes in gene expression, we considered every significant change in expression to be a valid change based on our rigorous statistical testing.
However the DASH has [ 18] excessive internal consistency, with a documented Cronbach Alpha value >0.95 [ 6, 8, 12, 19], the recognized upper limit for 'item redundancy' or the presence of too many items being too similar to enable a valid change to be detected [ 20].
We also had to demonstrate the valid application of the bMCU test both as a pre- and a posttest to reflect learning progress (valid change measure) and examine the test's reliability by interpreting item information curves.
The paired t-test was also considered to be inappropriate, because it is a measure of significant change instead of valid change, and it is dependent on the sample size of the study [ 18].
Overall, the majority of the focus group participants did not support the use of HPFI, although some were pragmatic, again saying that if HPFI are shown to be effective and cost-effective then they should be considered as a valid behaviour change intervention.

We lack a test with confirmed suitability for inter-individual comparisons independent of the test taker's individual characteristics (fair measurement), which not only enables one-time measurement but also can reflect learning progress (valid change measure).
