sFinal answer:
Without specific data on the total number of staff trained during 'week 1' and the number of working days in that week, it is not possible to calculate the average number of staff trained per working day.
Step-by-step explanation:
To determine the average number of staff trained each working day during week 1, specific data regarding the total number of staff trained in that week and the number of working days in the week is required. Unfortunately, none of the provided information contains direct data about the number of staff trained or the specific context of 'week 1.' Therefore, without additional context or numerical data related to the training that occurred in the specified week, it is not possible to calculate the average number of staff trained per working day.
Additionally, information like the recommendations from the International Association of Counseling Services or average work hours from the Bureau of Labor Statistics does not contribute to solving this particular query without knowing the total number of staff trained.
