The NAEP has two types of tests - a long-term trend assessment, and the main assessment[1]. The long-term trend is given less often (and rather sporadically recently), and 2023 is the most recent one available.
The main assessment has been performed every two years recently, so 2024 data is most recent. They can all be seen here[2].
