Since 2001, HELP has collected province-wide data for over 330,000 kindergarten children in BC, creating a unique and world-class data set that is not available in most other provinces or countries.

EDI Completion

The EDI questionnaire is completed online by kindergarten teachers for the students in their classroom in February

All about child development

The EDI questionnaire has 103 core items covering five core areas of development

The EDI is Voluntary

Schools, teachers, and parents/ caregivers are able to choose whether or not they participate

EDI Collection

Over 330,000 EDIs collected in BC to date

EDI Data

20 years of data for children across 8 provincial waves of data collection in BC

EDI Across Canada

EDI has been implemented in 12 of 13 provinces and territories in Canada, with over 1.3 million EDIs collected

EDI Data Collection Timeline

EDI data is collected on a three-year schedule called a “Wave” to capture sufficient data in all school districts in the province. Large school districts participate in just one of the years in a wave, usually in the first or second year. Smaller school districts will participate in multiple years of a wave, in order to ensure that the total number of children per neighbourhood in a wave is sufficiently high to allow a reasonable determination of change over time.

The current cycle is Wave 8, which started with the 2019/2020 school year, and will end with the 2021/2022 school year.

If you are an EDI School District Lead and need more information regarding your EDI data collection, go to the EDI Administration Blog.

How are data collected using the EDI?

Preparation for EDI Data Collection

The schedule for school district participation in a particular wave is decided by HELP and administrators from each school district. When a school district is scheduled to participate in the EDI that school year, a number of processes are put into motion for all involved parties, including:

  • School districts provide HELP with an electronic list of kindergarten students attending that year, along with some associated demographic data (e.g., date of birth, gender);
  • Kindergarten teachers participate in standardized training on how to complete the EDI; and
  • Parents and caregivers of kindergarten students receive information letters about the upcoming EDI data collection.

EDI Adminstrative Timeline:

  • September
    School districts invited to participate in EDI Implementation.
  • October-December
    School district EDI Leads participate in standardized training.
  • December
    Kindergarten teachers participate in standardized training. Parents/caregivers receive information about the EDI.
  • February
    Teachers complete the EDI questionnaire for students in their classrooms.
  • June
    School districts involved in data collection receive confidential school district reports.
  • Fall following Wave Completion
    At the end of a three-year data collection Wave, public reports are produced with data at the provincial, school district and neighbourhood-level.

EDI Questionnaire Completion

The EDI questionnaire is completed by kindergarten teachers in February of the school year, for each student in their class. The questionnaire is completed online, based on the teachers’ daily observations of their students since the start of the school year. Teachers are compensated for the time needed to complete the EDI, either by receiving a payment based on the class size or time off in lieu. The data collected are stored in HELP’s secure e-system. 

EDI is Voluntary, using Informed Passive Consent

Participation in the EDI is voluntary. Once a school district has signed on, schools, teachers, parents and caregivers are able to choose whether or not they participate. If parents or caregivers do not wish their child to participate in the EDI, they can inform their teacher or contact the EDI Implementation team directly.  

The EDI uses informed passive consent to collect data. This means parents and caregivers are fully informed about the EDI project and the use of the data through information letters sent from HELP and the school district before the questionnaire is completed, but they do not have to actively complete a consent form.  

Informed passive consent allows researchers to gather representative data for large populations — in this case with the EDI, for kindergarten students across BC. This is important to ensure the data accurately reflect what is happening in the lives of children and families in BC. As this study is considered low risk and provides beneficial community information, this consent model has been approved by the UBC Behavioural Research Ethics Board (BREB).
