Note: The sampling frame is the geographic area from which the schools were selected, as well as other criteria that defines which schools were available for selection.
Please choose the option that best describes your sampling frame:
Geographic area only
Geographic area and specific school type

1.3. Have you sent a detailed map showing the boundaries of your Phase 1 centre to the Co-ordinating Centre?

1.4 Were any schools excluded from the sampling frame before being approached to participate?
For example, schools might be excluded if the researchers know that they are located in areas with difficult access or if the children are unable to participate. These schools would then be left out of the sampling frame and not included in the selection process.
1.5 If yes, please give your reasons why these schools were excluded
from the sampling frame.
1.6 Did you reject any schools after they had been selected?
For example a school may have agreed to participate and you then found that the students were unable to complete the questionnaire because they were disabled.
