Youth in Transition Survey, 15 year-olds (Reading Cohort) (YITS)
Detailed information for 2000
The Youth in Transition Survey (YITS) is undertaken jointly by Statistics Canada and Human Resources and Skills Development Canada. This survey is designed to examine the major transitions in the lives of youth, particularly between education, training and work.

The Youth in Transition Survey (YITS) program is designed to examine the patterns of, and influences on, major transitions in young people's lives, particularly with respect to education, training and work. Human Resources and Skills Development Canada and Statistics Canada have been developing the YITS in consultation with provincial and territorial ministries and departments of labour and education. Content includes measurement of major transitions in young people's lives including virtually all formal educational experiences and most about-market experiences, achievement, aspirations and expectations, and employment experiences.
Age 15 was selected as the most appropriate for the adolescent group. At age 15, many youth are into high school, thinking about working part time, beginning to develop education and career aspirations and to establish some independence from parents.
PISA/YITS is one project, which consists of two parallel survey programs: the Programme for International Student Assessment (PISA) and the Youth in Transition Survey (YITS).
PISA is an international assessment of the skills and knowledge of 15 year-olds which aims to assess whether students approaching the end of compulsory education have acquired the knowledge and skills that are essential for full participation in society.
YITS is designed to examine the patterns of, and influences on, major transitions in young people's lives, particularly with respect to education, training and work. Human Resources and Skills Development Canada and Statistics Canada have been developing the YITS in consultation with provincial and territorial ministries and departments of labour and education. Content includes measurement of major transitions in young people's lives including virtually all formal educational experiences and most about-market experiences, achievement, aspirations and expectations, and employment experiences. The implementation plan encompasses a longitudinal survey of each of two groups, ages 15 and 18-20, to be surveyed every two years.
The 15 year-old respondents to the Reading Cohort (conducted in 2000) participated in both PISA (record number 5060) and YITS (record number 5058). Starting in 2002, they were followed up longitudinally by YITS (record number 4435). In 2009, a sub-sample of this cohort also participated in the Reading Skills Reassessment.

Data sources and methodology
The survey population for the Reading Cohort (15 year-olds) comprises persons who were born in 1984 and were attending any form of schooling in the ten provinces of Canada. Schools on Indian reserves were excluded, as were various types of schools for which it would be infeasible to administer the survey, such as home schooling and special needs schools. These exclusions represent less than 4% of 15-year-olds in Canada.
The Student Questionnaire and Parent Questionnaire were designed for paper and pencil collection. As the questions were developed, the associated logical flows, into and out of the questions, were specified to be user friendly. This included specifying the default questions or the next applicable question based on edits and checks. The initial version of the Student Questionnaire was focus-group tested. When applicable, questions used in other Statistics Canada surveys were implemented in YITS to improve comparability across surveys.
- YITS Student questionnaire: A YITS-specific 30-minute questionnaire was developed for items not covered by PISA. These items gather information on transition experiences, school engagement, attrition rate and activity (possible drop-out rate and reasons why), academic streaming, work load, programs for work preparation, labour force participation, education barriers, stressful experiences, school engagement, career aspirations, early formative influences, deviant behaviour, family relationships, living and learning conditions and other background variables. This information will be used to measure changes longitudinally.
- YITS Parent questionnaire: A 30-minute parent questionnaire, administered through a telephone interview, was used to collect information on the parents and their household to obtain more reliable data on socio-economic status.
Information on stratification can be found in the Cycle 1 - 15 year-old User Guide
This is a sample survey with a cross-sectional design and a longitudinal follow-up.
For Cycle 1 of the reading cohort, YITS was integrated with the OECD Programme for International Student Assessment (PISA - Survey #5060), a new project designed to measure students' skill levels in reading, mathematics and science.
The sampling plan is a two-stage probability sample. With this type of sampling plan, which enables future modelling of school effects, schools are selected at the first stage and then students are selected from schools at the second stage. Approximately 38,000 youth aged 15 from 1,200 schools participated in Cycle 1.
Data collection for this reference period: 2000-04-01 to 2000-05-31
Responding to this survey is voluntary.
Data are collected directly from survey respondents.
The PISA/YITS session occurs in the school and consists of: a two-hour written PISA assessment; a PISA Student Questionnaire (40 minutes); and a Youth in Transition Survey questionnaire (30 minutes).
In addition, school administrators were also asked to complete the PISA School Administrator's Questionnaire. This questionnaire took 30 minutes to complete.
Following the administration at school, parents of selected students were asked to participate in the YITS parent interview. This 30-minute interview was administered over the telephone by regional office interviewers.

A series of verifications took place to ensure that the records were consistent and that collection and capture of the data did not introduce errors. Reported data were examined for completeness and consistency using automated edits coupled with manual review. Some responses reporting uncommon values or characteristics were processed manually.
For quantitative variables such as income and earnings, imputation was performed to treat missing responses and/or outliers. The first step in the imputation process was a within-record imputation where missing information was replaced with values derived from the respondent's answer to other questions in the questionnaire using deterministic edit rules. The remaining missing data were imputed using nearest-neighbour donor imputation. Impudon was used for donor imputation.
Impudon is a generalized system for donor imputation built as a SAS macro using the version number 8 of SAS. It manages both numeric (positive, zero, negative) and categorical (or character) variables; uses matching fields that can be numeric and/or categorical; can use weights for relativizing the matching fields in the distance function between a recipient and a donor. There are many criteria of distance that can be used, and the user can specify more than one in an Impudon execution. The imputation groups are automatically generated from a variable list. The post-imputation edit rules can be of any type (linear, non linear, conditional, applying boolean operators, on numeric and/or categorical variables).
The estimation of population characteristics from a survey is based on the premise that each sampled unit represents, in addition to itself, a certain number of non-sampled units in the population. A basic survey weight is attached to each record to indicate the number of units in the population that are represented by that unit in the sample. This basic weight is derived from the sample design.
An initial weight was derived based on the two-stage sample design used for this survey. Components to this survey are PISA/YITS student and YITS parent. Weights were calculated on these components and on Mathematics and Science. A number of non-response adjustments were applied in order to obtain final weights. More than one adjustment was required because non-response can occur at various levels (e.g., schools, students, parents, non-consent of parents for students) for these respondents. BRR (balanced repeated replication) and Bootstrap replicate weights were derived to allow users to estimate CVs and standard errors for estimates.
Partial non-response can occur when a respondent is unwilling to answer sensitive questions, accidentally skips part of the questionnaire, or there is respondent fatigue or there are operational difficulties. Variables within a section tend to share a common subject matter and/or are used together for deriving variables about the same subject matter. If information is needed for only one variable at a time, the codebook should be consulted. Overall, item non-response is lower for the Parent questionnaire than it is for the Student questionnaire, with most variables having less then 1% missing data. The question where parents were asked about the month in which their spouse started working at their current job (PF48A) has the highest overall non-response rate at 22.6%.
Comparing counts to Census 2001:
When dealing with survey data, the sum of the final sample weights for a particular domain of the population will give an estimate of the population size for that domain. These totals were estimated for the gender and province domains and then compared to known population counts obtained from Census 2001 data for those same domains. Because a census count of 15 year-olds born in 1984 would include individuals that are not part of the target population (e.g. home schooled children, special needs students), the estimated totals based on the YITS weights should be less than the census totals.
Statistics Canada is prohibited by law from releasing any information it collects that could identify any person, business, or organization, unless consent has been given by the respondent or as permitted by the Statistics Act. Various confidentiality rules are applied to all data that are released or published to prevent the publication or disclosure of any information deemed confidential. If necessary, data are suppressed to prevent direct or residual disclosure of identifiable data.
Revisions and seasonal adjustment
This methodology does not apply to this survey.
Data quality is affected by both sampling and non-sampling errors. Non-sampling errors were minimized through testing (focus group, pilot survey and main survey); training of regional office staff; observation by head office personnel; tabulations of initial data; and adjustment of questionnaire specifications for future cycles. Quality assurance measures were implemented at each step of the data collection and processing cycle to monitor data quality. For sampling error, data reliability guidelines were established based on coefficient of variation (CV). It is recommended that any estimate based on fewer than 30 observations or with a CV greater than 33.3% not be released.
