Start Block
The Start Block is a special type of Call Block that will be activated at the beginning of an interview. Any questions or other objects located within the Start Block will be the first things that are processed when the respondent starts the interview.
The Start Block will be presented to the respondent when he/she enters the survey for the first time, and whenever the respondent returns to the questionnaire after a postponement. On returning to the questionnaire, the Start Block will present the answers that the respondent has entered previously. The respondent can then change those answers as required.
A Start Block cannot be deleted from the Questionnaire tree.
Note: If no questions are added to the Start Block, then it will simply be ignored.
A Start Block is of particular importance in CATI projects. It is here where we will define the sample information (background questions), check for the CATI collection mode, select the Extended Status (call outcomes), collect call attempt data and retrieve the interviewer name, etc.

End Block
An End Block is a special case Block that will be activated at the end of an interview. Any questions or other objects located within the End Block will be the last things that are processed when the respondent completes the interview.
Any questions contained within the End Block will be presented to the respondent when he/she leaves the interview either due to a postponement or because the questionnaire is completed. If the respondent returns to the interview later and again leaves it for any reason (perhaps this time the questionnaire is completed), then any questions in the EndBlock will present the answers that the respondent has entered previously. The respondent can then change those answers as required. An End Block object cannot be deleted from the Questionnaire tree.
Note: If no questions are added to the End Block then it will be ignored.
