Cohort 1953
Year 1966 the collection started for cohort 1953. It is like the first one an individual selection of children born on the 5th, 15th and 25th of each month in 1953. In addition to certain aptitude tests, the test booklet also contained questions concerning school motivation, interests and plans for the future.
Summary
Cohort 2 were born in 1953. In the spring term of 1966, the collection of data from the project's second cohort began and then applied to students born in 1953. The total number in the questionnaire is 10,723. As five years earlier, the majority were in 6th grade in the compulsory school system, but due of the introduction of compulsory school gradually, about 80 per cent now belonged to this school form, while only 20 per cent belonged to the older school form, the primary school.
In 6th grade, the students completed cognitive tests of an intelligence test nature, containing tasks of a verbal, inductive and spatial nature. At the same time, the students filled in a questionnaire with, among other things, questions about the school and plans.
Information about schooling, for example school form, class type, class structure, class character, year and grades are collected annually from 6th grade. As well as information about certain personal circumstances. Results from standardized knowledge tests are included. The tests are not the same as in 1961. Furthermore, it can be mentioned that partly different tests were given in compulsory school and primary school, respectively.

Cognitive tests
The Cognitive tests are of an intelligence test nature containing information of a verbal, inductive and spatial nature. These have been given at each collection in 6th grade and began with the evaluation in 1961. The three subtests and how they were developed are described in Svensson, A. (1964).
- Opposites: To enter the opposite of a particular keyword among four options
- Sheet metal folding: To find out which of the four figures you get, if you fold a pictured "sheet metal piece"
- Speech series: To supplement a series of speeches, where six numbers are given, with two more numbers

The number of variables for each cohort varies from a few hundred up to a couple of thousand. Some variables are present in all cohorts, others are only found in some. Some variables enable longitudinal studies, others only cross-sectional studies. UGU has developed an interactive list of variables to make it easier to find among the variables and see relationships between variables in different cohorts.
The variables are accessed through the links below. Questions about documentation are answered via e-mail to data controllers within UGU.
