It is important in the design of the vocabulary component of a teaching program that teachers are able to discover the state of their learners' vocabulary knowledge. It is also important that researchers can draw on a variety of vocabulary measures to investigate the nature of vocabulary growth. This study focuses on a controlled production measure of vocabulary consisting of items from five frequency levels, and using a completion item type like the following. The garden was full of fra flowers. The controlled-production vocabulary-levels test was found to be reliable, valid (in that the levels distinguished between different proficiency groups) and practical. There was a satisfactory degree of equivalence between two equivalent forms of the test.
