Oxford Reading Levels

Right reading level, right progress

Why use levelled readers?

For a child to become a confident and successful reader, they need to be presented with the right amount of challenge. Expertly levelled reading books help to develop children’s reading skills and a love of reading.

93% of UK teachers say that levelled reading books help to develop competent and successful readers.

What are Oxford Reading Levels?

Oxford Reading Levels is an expert system used to determine the level of many popular primary reading books from Oxford. The levels range from Level 1 to Level 20, supporting readers from Reception (Primary 1) to Year 6 (Primary 7). 

How are Oxford Reading Levels different to other systems? 

The Oxford Reading Levels system has been created over decades by our experts, authors and teachers. We have looked at the ‘science’ of books, including word levels and sentence characteristics, and the ‘art’ of books, including subject matter and visual elements. We have analysed over 2,000 books, 400,000 sentences and over 4,000,000 words. 

We develop our books with Oxford Reading Levels at their heart, making them truly effective in supporting children’s progress.

How do Oxford Reading Levels help children to read?

The Oxford Reading Levels Teacher’s Guide supports teachers in making the right judgement about what text a child should be reading. Then the Oxford Reading Levels progressively build fluency, comprehension and stamina. This leads to more children becoming successful readers.
