Science Process Skills Inventory (SPSI)

The inventory consists of eleven items, each representing a different skill in the science inquiry process. Youth are prompted to respond to each statement using a 4-point Likert scale indicating how often they practice each of the items when doing science: Never (1), sometimes (2), usually (3), and always (4). Recommended scoring of the SPSI is the calculation of a composite science process skills score. This is calculated by summing the individual ratings for each item. The score range for the composite score is 11-44.
