Between reading points (RP), a reading level test (RLT) specifies exactly three reading levels: math0, math5, and math29.

READING LEVEL TEST

Reading points (RP) specify

1+1+1

reading levels:

🚦 #Practice the #obvious reading level: #math29 🚥

That is (for instance): a specific stop sign, as a reading point identifier (RPI), specifies where to stop (math0), a driver (math5), and their immediate context (math29).
