Three instruments, each doing a different job.

Student Record
Tracks the materials themselves, section by section, from initial sounds through the consonant blends and phonograms. For each item the teacher enters the date it was introduced and the date the child worked it independently.

Skills Report
Rates the child across the skill areas at two points in the year, in separate versions for each age band. Ratings come from accumulated observation, not from a test.

Language Screen
Normative language behaviors by age, so a teacher can flag a child whose oral language lags before literacy instruction begins.

Control of Error
Every material carries its own control of error, so the child sees whether the work is right and corrects it without waiting for an adult.
