Systematic review under WWC 5.0 standards reports that Literacy First, a K–2 tutoring program offering "one- on-one tutoring offered in both English and Spanish for 20–30 minutes each day", showed strong ESSA evidence in three domains; the EGM shows improvement indices of +13 for phonics and related alphabetics, +14 for reading fluency and +8 for reading comprehension, and +8 (uncertain) for literacy achievement.
"This intervention had strong evidence of positive effects in phonics and related alphabetics, reading fluency, and reading comprehension."
