Telephone surveys can be a good choice for organizations who have the internal
resources for a large-scale survey. Otherwise, the organization may want to consider
outsourcing the telephone survey, as this research method generally involves a considerable time
and resource commitment, compared with in-depth interviews and focus groups. You may
conduct anywhere from 50 to 2,000 telephone interviews, depending on your research goals (up
to a point, the more interviews you conduct, the more accurate the findings). You may conduct a
telephone survey with one type of respondent (e.g., local educators), or with several types of
respondents (e.g., local educators, local policymakers, and local after-school program operators)
to obtain different perspectives on your topic.
