Overview of Assessment

Students must demonstrate an understanding of all elements of competency to be deemed competent.

A range of assessment methods are used to assess practical skills and knowledge, for example:

  • direct questioning combined with review of portfolios of evidence and third party workplace reports of on-the-job performance by the candidate
  • review of authenticated documents from the workplace or training environment
  • demonstration of techniques

Students are advised that they are likely to be asked to personally demonstrate their assessment work to their teacher to ensure that the relevant competency standards are being met.

Assessment Tasks

You are required to complete 3 tasks. You must successfully complete all 3 tasks to be deemed competent in this unit.

TASK 1 - Class Exercises (Due Dates: Refer to Teaching Schedule)

For this assessment task you will be expected to complete a variety of exercises which you have performed in the classroom and demonstrate these on a regular basis. These exercises will cover all elements of this competency from gathering data to designing and testing small databases.

In order to be deemed competent in this task you will be expected to demonstrate proficiency in a variety of areas including the following key areas:

Other Information

Submission Requirements

Assessment tasks need to be submitted via Blackboard.

You should:

  • Ensure that you submit assessments on or before the due date. If your performance in the assessment is affected by unexpected circumstances, you should consider applying for Special Consideration. Information on the process and application forms is available at;ID=ls0ydfokry9rz website.
  • Always retain a copy of your assessment tasks. (hard copy and soft copy)
  • When you submit work for assessment at RMIT University you need to use a cover sheet that includes a declaration and statement of authorship. You must complete, sign and submit a cover sheet with all work you submit for assessment, whether individual or group work. On the cover sheet you declare that the work you are presenting for assessment is your own work. An assignment cover sheet for submission of work for assessment is available on blackboard.

Each page of your assessment should include footer with your name, student number, the title of the assessment, unit code and title and page numbers. For example, Julie Macpherson, 324567, Task 2, OHS2345C Ensure safe workplace, Page 1 of 10.

Marking Guide (Competency):

Vocational Education and Training (VET) is based on current industry needs and the focus on preparing you for the workplace. Because VET courses are informed by practical application of knowledge and skills, they are based on a system known as ‘competency based training’ (CBT).

So when you are assessed in VET it is about whether you are competent to do the job, as well as having a firm grasp on the knowledge and skills required to do that job, as opposed to traditional curriculum based education settings that are often based on knowledge retention.

You need to demonstrate you are competent in each element of the unit of competency you are studying.

You will receive feedback on each assessment task that will inform you whether you are competent or not and how well you are performing. Once competent in all elements of the unit you receive a competency grading.

Please refer to the Final Grades table below.

Marking Guide (Grading):

After achieving competency we then grade your performance in the unit; this gives you the opportunity to have the level of your performance formally recognized against industry standards and employability skills.

The grading is according to the following criteria:


We are looking for a high level of ability to complete all tasks independently as per the specifications given to in class. You should endeavour to demonstrate a high level of initiative in your approach to planning and developing viable and feasible Websites for the various business scenarios investigated.


We are looking for depth of understanding of the key concepts and knowledge required in planning and developing a variety of business Websites. You should be able to demonstrate a thorough understanding of feasibility concepts and the HTML and CSS you have learnt in all assessment tasks.


We are looking for appropriate use of the latest techniques in HTML and CSS to produce effective business Websites as per client requirements outlined in a feasibility study. You should aim to consistently demonstrate your skills in each assessment task.

You also need to be able to overcome the various problems which that can arise in developing a business Website, in particular page layout problems. You will need to demonstrate a degree of perseverance, and be able research possible solutions via the Web.


You should aim to attend all class sessions and save your solutions to all exercises and assessment tasks you have completed, for example on your home drive or USB device. An organised folder structure is highly recommended.

It will be very advantageous to prepare for and review class materials using suggested resources, such as the recommended textbook or Websites indicated by your teacher.

We also expect to see ongoing progress your portfolio of documents for the project, full utilisation of Blackboard as per course guidelines and timely submission of all assessment tasks.


We expect to see contributions to relevant discussions in class and with your team members. For the project in particular you will need to work effectively in a team, and manage your work to ensure timely completion and client approval. You should therefore also liaise with your client on a regular basis throughout the project.

Final Grades Table:
