Quality Assurance processes • Broad consultations with stakeholders in the selection of topics-relevant topics selected • Involvement of stakeholders in the design of census instruments (questionnaires, manuals, etc.) • Involvement of stakeholders in census mapping • Early start of census mapping • Effective supervision in the delineation of EA maps

  5. Quality Assurance processes • Effective supervision in the production and printing of EA maps • Test census questions and carry out pilot census • Recruit high caliber field staff • Carry out sufficient and effective training of field staff • Involve stakeholders in enumeration • Put in place EA tracking system

  6. Quality Assurance processes • Effective supervision of data collection (1:5)-supervisors required to edit all questionnaires and conduct spot checks • Issue certificate of enumeration to floating population • Stickers on walls to indicate enumeration has been done • Involvement of external supervisors/monitors • Set-up call centres where queries from the public are addressed

  7. Quality Assurance processes • In addition to the normal control measures, quality control teams were set up after the end of enumeration to check on listing and enumeration in selected areas in the case of the 2010 PHC • Timely choice and testing of technology for data processing OR data collection equipment • Control forms for movement of field logistics, especially questionnaires • Evaluation of data quality using PES and demographic methods
