History and scholarship
Spence's (1973) signalling theory explains portfolios as signals beyond degrees; Schön (1983) and Kolb (1984) underpin showing process and reflection. Wiggins (1990) argued for authentic assessment, Paulson et al. (1991) defined portfolio conditions, and Barrett (2007) studied e-portfolios.

Typically each project shows context, problem, your role, process, results and lessons; depth over quantity. Laws, programmes, visa rules and hiring practice change; check official notices, current law and actual postings.
In practice
UX shows research, marketing campaigns, developers a GitHub portfolio; clarify team contributions.
