Unfortunately, even though roughly 35% of all OLPC computers went to Uruguay, a 2013 study by the Economics Institute (University of the Republic, Uruguay) of the Ceibal plan concluded that use of the laptops did not improve literacy and that the use of the laptops was mostly recreational, with only 4.1% of the laptops being used "all" or "most" days in 2012. The main conclusion was that the results showed no impact of the OLPC program on the test scores in reading and math.
