In more detail
When codes are first clustered in phase 3, the themes that result are candidates. Some will hold up in review, some will be merged, split or set aside, and some will turn out to be topics rather than themes.
Treating early themes as candidates keeps the analysis open. It reminds the researcher that the structure is still being developed, which is the point of phase 4.
In Themescape
The template has a candidate_theme column for a quote whose final theme is not yet decided. It is used when the theme column is blank, and the viewer shows the quote under that working theme. Quotes with neither a theme nor a candidate theme are grouped under Uncategorised.
