Each level of PTE Young Learners (except Level 1 Firstwords) is an ongoing, incremental and cumulative body of knowledge, not a discrete category without relation to prior learning. Thus, as test takers enter each new level of PTE Young Learners, it is presupposed they are familiar with, and can successfully engage in, the communicative tasks, language skills and structural and language content of the levels which precede their current area of study.
