Assessment tool

Version 1.0
Issue Date: July 2021

Not applicable.

This competency standard covers the process of maintaining interior plant displays in buildings and offices. Maintenance involves watering, feeding and other plant treatments necessary to maintain the health and appearance of indoor plants.

Indoor plant maintenance is usually performed under routine supervision with intermittent checking. Responsibility for some roles and co-ordination within a team may be required. Competency is demonstrated by the application of knowledge and skills to a range of plant maintenance tasks and roles usually within established enterprise guidelines.

You may want to include more information here about the target group and the purpose of the assessments (eg formative, summative, recognition)

Evidence Required

List the assessment methods to be used and the context and resources required for assessment. Copy and paste the relevant sections from the evidence guide below and then re-write these in plain English.

What evidence is required to demonstrate competence for this standard as a whole?

Competence in maintaining indoor plants requires evidence that the feeding, watering, cleaning, pruning, and treatment needs of indoor pot plants and displays can be met.

The skills and knowledge required to maintain indoor plants must be transferable to a different work environment. For example, if plants can be maintained in an atrium with high intensity natural light, it must also be evident that plant maintenance can be undertaken in an office with low light intensity.

What specific knowledge is needed to achieve the performance criteria?

Knowledge and understanding are essential to apply this standard in the workplace, to transfer the skills to other contexts, and to deal with unplanned events. The knowledge requirements for this competency standard are listed below:
1. identification and characteristics of common indoor plants and their culture
2. growth requirements of indoor plants
3. light and moisture tolerance/intolerance for common indoor plant species
4. acclimatisation techniques for indoor plants
5. common problems that may occur with indoor plants and their treatment
6. operations and maintenance of a range of irrigation/subirrigation systems used for watering indoor plants/displays
7. methods of disposing of waste to minimise damage to the environment.

What specific skills are needed to achieve the performance criteria?

To achieve the performance criteria, appropriate literacy and numeracy levels as well as some complementary skills are required. These include the ability to:
8. participate in teams and contribute to team objectives
9. interpret enterprise work procedures
10. communicate with clients, team members and supervisor
11. measure quantities and calculate application rates.

What processes should be applied to this competency standard?

There are a number of processes that are learnt throughout work and life, which are required in all jobs. They are fundamental processes and generally transferable to other work functions. Some of these are covered by the key competencies, although others may be added. The questions below highlight how these processes are applied in this competency standard. Following each question a number in brackets indicates the level to which the key competency needs to be demonstrated where 0 = not required, 1 = perform the process, 2 = perform and administer the process and 3 = perform, administer and design the process.

1. How can communication of ideas and information (1) be applied?

Ideas and information relating to indoor plant maintenance activities and problems encountered should be discussed with other members of the work team and the supervisor.

2. How can information be collected, analysed and organised (1)?

Enterprise work procedures, such as watering plan or nutrition schedule, should be consulted, interpreted and applied to coordinate indoor plant maintenance activities with further clarification sought from the supervisor where necessary.

3. How are activities planned and organised (1)?

Work activities for indoor plant maintenance routines may need to be organised around client requirements, and there may be some responsibility for coordinating work activities with other members of the work team.

4. How can team work (1) be applied?

Indoor plant maintenance activities may involve working with other members of a team to complete operations within the daily work routine.

5. How can the use of mathematical ideas and techniques (1) be applied?

Calibrating spray equipment and determining quantities and application rates for treatment of indoor plants will require mathematical application.

6. How can problem-solving skills (1) be applied?

Problems relating to maintenance of the growing environment, the plants, treatments, watering, tools and equipment, workplace safety and other team members may arise during the maintenance of indoor plants.

7. How can the use of technology (1) be applied?

Technology may be applied in the preparation, use and maintenance of horticultural and test equipment.

Are there other competency standards that could be assessed with this one?

This competency standard could be assessed on its own or in combination with other competencies relevant to the job function.

There is essential information about assessing this competency standard for consistent performance and where and how it may be assessed, in the Assessment Guidelines for this Training Package. All users of these competency standards must have access to the Assessment Guidelines. Further advice may also be sought from the relevant sector booklet.
