Frequently Asked Questions
Common questions about learning loss and this data.
According to McKinsey research, students lost an average of 12 weeks of learning overall, with math losses particularly severe at 15-24 weeks (a quarter to half a school year). Reading losses averaged 9 weeks. The 2024 NAEP showed 8th grade math scores dropped 8 points and reading dropped 5 points compared to 2019.
Recovery has been slow and uneven. The 2024 NAEP results show students remain significantly below pre-pandemic levels. Without accelerated interventions, McKinsey projects fourth-grade math won't recover until 2036, and eighth-grade math won't recover until 2050.
Math suffered approximately twice the learning loss of reading. Students were 15-24 weeks behind in math compared to 9 weeks behind in reading. The 2024 NAEP shows 45% of 12th graders scoring below basic in math—the highest percentage ever recorded.
Learning loss has disproportionately affected disadvantaged students. Losses for students in the bottom 10% grew 70% larger between 2022 and 2024, while the bottom 25% saw losses grow 25% larger. This has created a 'K-shaped recovery' where high-achieving students improve while lower-achieving students continue declining.
McKinsey estimates that by 2040, pandemic-related learning delays could cause $1.6 trillion in annual global economic losses (0.9% of GDP). Individual students could lose $54,000 to $69,000 in lifetime earnings without intervention.
High-dosage tutoring (3+ times per week during school) has shown the strongest results, with research showing it can double or triple student learning in a year. McKinsey estimates strategic use of ESSER funds across proven interventions could recover 90% of learning delays.
The pandemic erased more than 20 years of progress on NAEP assessments. Reading scores in 2024 fell below even the 2022 levels that many hoped would be the low point, demonstrating continued deterioration rather than recovery.
Only 31% of fourth-graders scored at or above NAEP reading proficiency in 2024, down from 35% in 2019. At the eighth-grade level, a record 33% of students are not even reading at the Basic level—the highest percentage ever recorded.
More than 17 million students in the United States experienced more than half a year of pandemic-related learning delay. Globally, the pandemic affected over 1.6 billion students across 190 countries at its peak.
At historical improvement rates, McKinsey projects fourth-grade math recovery by 2036, fourth-grade reading by 2044, and eighth-grade math by 2050. However, strategic interventions like high-dosage tutoring could significantly accelerate this timeline.
