Richmond Publishing makes the "Lighthouse" workbook series, of which "Lighthouse 3" is a part. The program is designed to help non-English speakers learn the English language.
Brendan Dunne and Robin Newton collaboratively wrote the 6 level Lighthouse series with the aim of providing students a step-by-step guide for learning English. The program offers reading, writing and listening materials to help students better grasp English grammar in real world situations.
The program is designed for primary school students who have completed the pre-primary program as well as the previous books in the series. Richmond Publishing offers secondary school programs in addition to other primary school programs.
