There can be literary texts on the rSAT, but there is a backstory here.
One of the hallmarks of Common Core is a sharp decrease in literary and an increase in “informational” texts, especially in the upper grades. The claim of Common Core proponents is that non-fiction is more important for college- and career-readiness than is fiction. The emphasis on non-fiction is also connected to the changed vocabulary landscape of the rSAT, because complex literary texts generally contain different vocabulary items than do informational texts.
Many ELA experts have criticized these aspects of Common Core. They have pointed out that literature strengthens imagination, moral sense, and a certain kind of creative critical thinking in ways that non-fiction does not. Sandra Stotsky, the member of the Common Core ELA Validation Committee with the most academic qualifications, refused to sign off on the standards and has since become a vehement critic. She also strongly disagrees with the Common Core approach to vocabulary; she claims numerous studies have show that vocabulary is the foundation of reading comprehension, and that crucial vocabulary is built not in only context but by looking words up in the dictionary. Peter Wood, president of the National Association of Scholars, has said that the excessive emphasis on rhetoric, evidence, and argumentation in Common Core ELA tries to turn students into lawyers.
