PISA: 15-year-olds by reading proficiency level (%). Below Level 1B
Wat erin zit
Percentage of 15-year-old students scoring students below the lowest proficiency level (1B) on the PISA reading scale. Students with scores below Level 1b (less or equal to 262 points) usually do not succeed at the most basic reading tasks that PISA measures. This does not necessarily mean that they are illiterate, but that there is insufficient information on which to base a description of their reading proficiency. 2000, 2003, and 2006 PISA assessments used a different reading proficiency scale (Below Level 1 to Level 5) than later assessments, which use a reading scale from Below Level 1B to Level 6. Because an equivalent proficiency level to "Below Level 1B" and Level 1B were not calculated for the 2000, 2003, and 2006 PISA Reports, the data are not currently available for those years. Use caution in comparing proficiency scores across years. For more information on comparability of results, consult the PISA website: http://www.oecd.org/pisa/.
