At the same time, because each CBM test assesses the many skills embedded in the annual curriculum, CBM yields descriptions of students' strengths and weaknesses on each of the many skills contained in the curriculum.
Certainly, a number of PTE measures have been developed, but empir ical evaluation of their psychometric properties is the ex ception rather than the rule.
