Parece que a Suécia melhorou no PISA porque manipulou os resultados

... subtraiu os resultados dos 11% piores, para esconder o facto dos imigrantes/refugiados que entraram no país nos últimos anos terem feito baixar a média de resultados. O sistema de ensino sueco está concebido para suecos, quer dizer, alunos de famílias com boas condições sociais e não para pobres que não dominam bem a língua.


According to the newly-published results of the Programme for International Student Assessment (PISA), which tests 15-year-olds' scholastic success in reading, mathematics and science in 79 countries around the globe, Sweden has upped its performance from “well below average” to “above average”.

The test results of wholly 11.1 percent of Sweden's 15-year-old were removed from the survey, up from 5.7 in 2016 and the highest of all the 79 participant countries who have an average percentage of exclusions of 4.0 percent. Admittedly, poor language skills due to immigration are the main reason for it.

“There is reason to believe that the increased rate of exclusion between 2015 and 2018 is mainly due to an increased proportion of students with limited command of the Swedish language. This is due to the migration flows that caused the great refugee crisis in 2015 and which is visible in the statistics of new arrivals in Swedish schools”, the Swedish National Agency for Education wrote in its report.

The report authors noted that Sweden stressed that foreign-background pupils, whose share has increased due to high immigration, tend to perform worse than students born in Sweden.

“Since foreign-born pupils with a foreign background tend to average lower results, an increased proportion will have a negative impact on the national average,” the report said.

Without the demographic change, the positive education trend could have been much more pronounced, national broadcaster SVT reported.

The idea that Sweden may have been doctoring its records to make them look better sparked outrage.

“The former alliance parties love to take the honour for Sweden moving up a little in the PISA survey. Do you also take credit for the fact that 11% of Sweden's 15-year-olds do not master the Swedish language? The National Agency for Education says it depends on the large immigration”, journalist Mira Aksoy tweeted.

​“According to PISA's own rules, a maximum of 5% of the students may be excluded from the survey. How Sweden has managed to exempt 11% should be a matter for journalists to investigate,” advocate and Moderate Party politician Henrik Sundström tweeted.
