The overall aim of this study is to analyse and describe reading ability from the second to sixth year of schooling in Sweden (ages 8–13). An intro­ductory study presents the pupils’ reading profiles and also the extent to which teaching in reading comprehension is given at their schools. In a second study, the results and effects of the national test in Swedish in grade three (age 9) are studied and compared with other recognised test data on the development of children’s reading.

A total of 428 pupils at four schools participated in the study. Each child was tested once a year during two consecutive school years. In addition to collecting results on the national test for all the pupils in their third year, standardised tests of word decoding ability and reading comprehension were administered to all students in the study. A questionnaire dealing with teaching reading and skills development was answered by 23 teachers.

The study reveals that there are stronger links between phonological tasks and reading comprehension for pupils in their first three years than for those in years 4–6.

The study also shows that the national test identifies some pupils with reading difficulties but not all of them. A number of pupils who have problems with word decoding nevertheless attain the national test threshold for reading comprehension tasks in the third year. There are also pupils who cannot manage the age-adapted reading comprehension tasks but who still pass the national test in their third year.

The findings reveal that teachers work with reading comprehension exercises to only a small extent in both the first three years and second three years of schooling.

The study indicates the importance of using a diagnostic approach, so that early and effective measures can be adopted to prevent the emergence of reading comprehension problems.

The national standardised literacy assessment (NSLA) for Swedish Language was introduced in 2009 as a grade-three compulsory assessment and includes the assessment of reading ability. It was introduced as a measure of relatively early identification of reading difficulties among nine-years old students. The primary objective of this study was to examine whether the NSLA is able to identify students with word decoding problems from a sample of third graders (N = 112; n = 57 girls; n  = 55 boys) attending six schools in a Swedish municipality. Eleven students (10%) performed below the cut-off value for word decoding ability in students of this age group. Only three of these students were identified as not achieving the goals posed by the NSLA. In contrast, eight students with low word decoding ability managed to meet the NSLA requirements. Gender differences were observed, since all of the students who passed the NSLA, notwithstanding having low performance in WD, were boys. Although the NSLA was specifically introduced at this level to identify weakness in reading at an early stage, the results of this study indicate that approximately three quarters of students with poor word decoding ability may remain unidentified by the NSLA. These findings call into question the validity of the NSLA in recognising pupils in need of additional support in reading.

Language abilities in preschool years, including those measured with letter knowledge, are predictors of reading development in later school years. The aim of this study was to investigate variation in children's language abilities before they started school in relation to gender and neighborhood level socioeconomic status (SES). Schools from three municipalities with varied resources and living conditions participated in this study. The participants were 231 children 4-6 years old (girls n = 117, boys n = 114; mean age 4.8 years old; SD = 6 months). In this cross-sectional study, children took the Rapid Automatized Naming (RAN) object test and a Letter Knowledge task. Results showed no significant differences in task performance between boys and girls. Children attending preschools situated in average to above average SES areas had higher scores on the RAN object task compared to those who attended preschools located in low SES neighborhoods. Finally, a significant association was found between children's first language and SES. The implications of these results are explored in this article.
