Abstract A team of facilitators describe the process and
content of portfolios they create for families attending weekly
playgroup sessions based on the philosophy and practices of
the Parents Interacting with Infants (PIWI) model. The parent–child
portfolios are a form of authentic assessment and
highlight children’s development within the context of parent–child
relationships. Facilitators complete weekly observations
of parent–child interactions, which allow them to
monitor children’s progress on goals set by parents, evaluate
their own practices, and plan future playgroup sessions.
