Remote learning is less effective than in-person schooling for K–12 students

What's this about?

People disagree about whether remote learning works less well than learning in a school building. The answer may change by student, school, and online plan.

What supporters say

• During large school shutdowns, students made slower progress and got lower test scores.
• Younger students and students with fewer home resources may face more trouble with online learning.
• Students in full-time online schools often got lower test scores than students in regular schools.

What critics say

• Online lessons during a crisis differ from well-planned online schools with trained staff and good tools.
• Some students may learn better online because flexible lessons can fit their needs and lives.

How to read this

The number of points on each side does not show who is right; stronger proof matters more.

The bottom line

Overall, the evidence shows that remote learning often leads to weaker results than classroom learning. However, remote learning does not harm every student, and poor crisis planning may explain some results.

The claim that remote learning is less effective than classroom teaching is broadly supported as an average tendency, but it is not true for every student or every online program. The key question is whether lower results come from remote instruction itself or from the difficult conditions in which it is often delivered.

The case for

The strongest evidence comes from the pandemic, when many schools closed their buildings and moved lessons online. Assessment data and international studies found slower learning progress and lower test performance during these periods. Reviews covering many studies also reported harmful effects on learning and school performance. Together, these findings show a broad link between largely remote schooling and weaker achievement, although differences in closure length, family circumstances, testing and school responses make it difficult to isolate the effect of remote teaching alone. 1 (see Figure 3)

Evidence from established full-time virtual schools also points in the same direction. In 2018–19, the U.S. Government Accountability Office reported that students in virtual schools had lower state-test scores and were less likely to take the tests than students in traditional schools. Other research has found lower achievement in some virtual charter schools. Online attendance and participation can also be harder for schools to track, providing one possible explanation for weaker results. But these comparisons do not prove that remote instruction caused the entire gap. 2

The challenges are not shared equally. Students without reliable internet or devices, adult help, quiet study space or strong self-management skills may struggle more when learning from home. Data from the OECD and analyses of pandemic disruption suggest that remote learning widened some existing gaps, with outcomes depending heavily on access, family support and the quality of home learning conditions. 3 (see Figure 4)

The case against

The main objection is that emergency remote teaching is not the same as well-planned online schooling. Pandemic lessons were often introduced during a crisis, alongside disrupted routines, limited services, family pressures and falling student engagement. Poor results under those conditions cannot confidently be treated as proof that established online programs are inherently worse.

Research on full-time K–12 online education remains limited and uneven. Its success appears to depend on course design, teacher preparation, regular interaction, monitoring and student support, as well as the characteristics of the students involved. Students whose teachers stayed available during school closures generally performed better and felt more confident learning independently. This suggests that the quality of support can matter as much as the delivery format. 4

Some students may also benefit from online flexibility, particularly those who cannot regularly attend a conventional school. However, the evidence offered for this benefit is mainly based on what online learning can make possible, rather than proof that it produces better average academic results. Comparisons between virtual and traditional schools are also complicated by student selection: families may choose online schools for reasons linked to achievement, health, mobility or other circumstances. Differences in attendance, test participation and accountability can further distort the comparison. 5

A major evidence gap remains. Few rigorous studies separate established remote schooling from emergency closures while also accounting for which students choose or are placed in virtual schools. A Campbell Collaboration protocol has said that the available comparative evidence is uncertain enough to require a systematic review. Concerns about conflicts of interest and limited generalizability also mean that apparent differences should not automatically be blamed on the delivery method itself.

The bottom line

The evidence favours the claim, but only with important qualifications. Remote learning is associated with lower achievement during pandemic disruptions and in some full-time virtual-school comparisons. Confidence is high that remote schooling imposed during a crisis, or delivered with weak support, can produce substantial learning losses.

The evidence is weaker for the broader claim that remote learning is always less effective than comparable, deliberately designed in-person schooling. The observed disadvantage may reflect a mixture of poor implementation, unequal access, weaker engagement, student selection and differences in measurement. The fairest conclusion is that remote learning tends to perform worse when design, monitoring or support are weak—but the mode itself does not determine outcomes for every program or every student.
