Simply fi nd the number of correct answers the student produced along
the top of the chart and the number of total questions on the worksheet
or activity along the left side. Then fi nd the cell where the column and

Conversion Chart, you can easily convert any raw score, from 0 to 20,
into a Tens score.

with assessments that have a defi ned number of items (such as written
assessments). However, teachers are encouraged to use the Tens system
to record informal observations as well. Observational Tens scores are
based on your observations during class. It is suggested that you use the
