Yes of course. When you get started, you will be able to add a note about your child’s reading level so you can let us know where you think they should start. Please keep in mind the advice about how you know if a reading level is too easy, hard or just right.
All schools encourage children to read at home. Many schools insist that the child stays on the school assigned reading level in school (they may have many reasons for this such as wanting the child to explore a different genre at that level or they are focusing on expression and fluency) but they are more than happy for you to pursue your own books at home. These could be at a different reading level for consolidation or extension. Remember all reading practise is great practise!
