- Linguistic Knowledge is the Praxis 5195 topic nobody names. It has no line on your score report — but it's tested inside every Listening selection, every Reading passage, and every constructed response for register. Combined, LK content touches roughly 18 items across four of the five test sections.
- The Linguistic Knowledge Course teaches the 5 LK Archetypes framework — grammar-in-context, cohesive devices, vocabulary and polysemy, sociolinguistic inference, and regional variation — with the exact spotting reflex and 30-second solve that carried my Listening + Reading combined score up 10 raw points on retake. 6 video modules · note-catchers · reference cards · Pre + Post Assessment. $69.
