Delphi method

Primary round two

Modifying instrument

The second questionnaire was modified based on consensus or recommendations from the panel on the items in round one. For example, most panelists commented that one particular item was very similar to another in the list. Hence, the 2 items were combined. In the first round, one item was considered to have already reached consensus as it has been rated 'important' by all 9 panelists. Therefore, in the second questionnaire, it was highlighted to remind the panel that they did not need to consider this item again.

Analyzing and interpreting data

The data were interpreted after the second round of the survey. Any item scoring a response rate of 75% or more in the '4-5' category on the Likert scale was considered to have reached consensus by the panel. According to the literature on Delphi, 75% is an acceptable cut-off point (Jacob 1996). There were 11 items that reached consensus by this method. These items were then included when developing the assessment rubric in the following phase. The items which received a response rate of 75% or more in the '1- 2' category indicating unimportance were discarded. Table 1 shows the survey results of rounds 1 and 2.

As seen from the above table, after two rounds of survey, 11 items out of 25 reached consensus as important criteria. A further 6 items were dropped because they were rated unimportant by a majority of the panelists.
