Evidence Guide


The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, range statement and the Assessment Guidelines for the Training Package.

Overview of assessment 

Critical aspects for assessment and evidence required to demonstrate competency in this unit 

Evidence of the following is essential:

  • plans within activity constraints and guides and monitors groups in a safe and professional manner
  • applies contingency management techniques to deal with a range of problems and issues that commonly arise during snorkelling activities
  • encourages and responds to group feedback and evaluates and reflects on own guiding performance to identify strengths, weaknesses and areas that need improvement.

Context of and specific resources for assessment 

Assessment must ensure the safe guiding of groups in snorkelling activities that reflect the needs of a range of participants to demonstrate competency and consistency of performance.

Assessment must also ensure access to:

  • a suitable snorkelling site with either open or confined water that enables the demonstration and practice of snorkelling techniques
  • participants to take part in the snorkelling activity
  • snorkelling, safety, rescue and first aid equipment
  • resources and information regarding participants and location to plan, guide and document snorkelling activity for a variety of participants.

Method of assessment 

A range of assessment methods should be used to assess practical skills and knowledge. The following examples are appropriate for this unit:

  • observation of planning and guiding processes and interacting with a group of participants, including conveying information for safe participation
  • oral or written questioning to assess knowledge and application of legislation and organisational policies and procedures to enable safe conduct of all snorkelling activities
  • observation of dealing with contingencies such as changing conditions and equipment failure
  • review of snorkelling activity plans
  • third-party reports from a supervisor detailing performance.

Holistic assessment with other units relevant to the industry sector, workplace and job role is recommended, for example:

  • SROSNK201A Participate in snorkelling activities.
