How do Literably's levels correlate to other leveling systems?

The table below describes how Literably's A-Z levels (which are the same as those of Fountas & Pinnell) correlate with other leveling systems. Please note that all correlations between leveling system are very rough.  The Literably level refers to the instructional level, NOT the independent level. If your students are at a Pre-A level, you may consider Literably's Foundational Skills assessments for monitoring your students' progress in phonics and phonological awareness.
