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 2 tasks. You must successfully complete each task to be deemed competent in this unit.

TASK 1 - Database Project (Due Dates: Refer to Teaching Schedule)

The task will be submitted in three stages. Stage 2 is an individual submission and Stage 1 & 3 are team submissions.

For this assessment task you will be asked to plan and develop a database for a library from scratch in consultation with key stakeholders. You will first need to identify information sources, gather data and confirm client database requirements. 

In order to be deemed competent in this task you will be expected to demonstrate proficiency in a variety of areas including (and not limited to)  the following key areas:

  • Skills in gathering and analysing data to determine requirements
  • Ability to produce ERDs for a wide variety of scenarios
  • Ability to build and implement a database using established design.
  • Ability to normalise your tables to store data effectively
  • Ability to create objects such as forms and reports
  • Ability to write programs to simulate data and build flexibility in implementation
  • Ability to evaluate current IT infrastructure and develop IT services to meet future enterprise requirements.
  • Documentation of security and recovery procedures and training requirements.

Work for each stage of the project (outlined below) should be submitted on the due date, as per the Teaching Schedule. You will be expected to submit and retain soft copies of any documents required. In some cases printouts may be required.

Project Stage 1 (Team): Initial draft of proposal outlining details elicited by questioning the client

  • Area of business operations, as well as purpose & scope of database project
  • Key library processes such loans, payments , search & hold.
  • Technical constraints including hardware & software e.g. DBMS
  • Any key business rules & particular database requirements
  • Any issues requiring further clarification from key stakeholders (further questions)
  • Team member responsibilities & communication plan
  • Sample business documents e.g. forms & reports from current system
  • Analyse strategic plan of the organisation, identify IT gaps and document the effect of IT developments.

Project Stage 2 (Individual): 

  • Complete template (will be provided) for database design includes first draft of ERD (with cardinalities) created in Visio.
  • Prototype with sample data built in MS Access
  • Evaluate effect of IT changes.

Project Stage 3 (Team):

  • Complete template (will be provided) for final version of database, including forms and reports
  • Final project documentation, including access, security, and training.
  • Evaluate, effect and develop action plans.

Students will receive feedback or confirmation at each stage in relation to client requirements. In many cases changes or modifications will be required. It is therefore vital that any design documentation and other work required for each stage be submitted in a timely manner.

TASK 2 - Skills Review (Date: Refer to Teaching Schedule)

  • You will be asked to develop data models and design data structures, for scenarios under test conditions.
  • You will be required to implement the model with sample data on a given platform.
  • You will be required to identify gaps in IT infrastructure.
  • You will also need to be able to analyse simple data in order to confirm database requirements.
  • Some knowledge of security concepts and procedures will also be required.


Assessment Matrix

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 http://rmit.edu.au/browse;ID=ls0ydfokry9rz website.
     
  • Always retain a copy of your assessment tasks. (hard copy and soft copy).
  • 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.
     
  • 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.


Resubmission Guide:


Once a student has submitted an assessment task, a resubmission may be granted if deemed NYC. On resubmission, a student will not receive a grade higher than CAG (Competency achieved).

 
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 will include the following criteria:

1. LEVEL OF INDEPENDENCE, INITIATIVE, ENTERPRISE AND PERFORMANCE OF WORK TASK

We are looking for a high level of ability to complete all tasks independently as per the specifications. You should endeavour to demonstrate a high level of initiative in your approach to gathering data and designing your databases, particularly in the team project.

2. DEMONSTRATED BREADTH OF UNDERPINNING KNOWLEDGE AND A WILLINGNESS TO CONTINUE LEARNING

We are looking for depth of understanding of the key concepts and knowledge required to gather data and design a database. You should be able to demonstrate a thorough understanding of information gathering and data modelling techniques in each of the assessment tasks.

3. TECHNIQUES & PROCESSES, TECHNOLOGY SKILLS AND PROBLEM SOLVING

We are looking for a high level of skill in data gathering and database design techniques. In particular you will need to be familiar with the appropriate technology such as modern database management systems, including multi-user systems.

You will need also need to show an understanding of the kinds of problems that can arise in designing a  database and how these might be addressed. You will need to demonstrate a dgree of perseverence, and be able to use normalisation techniques to improve your designs.

4. WORK ORGANISATION, PLANNING AND SELF MANAGEMENT

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.

5. COMMUNICATION, PEOPLE NETWORKING, LANGUAGE AND INTERPERSONAL SKILLS AND TEAMWORK

We expect to see contributions to relevant discussions and scheduled group sessions. 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 key stakeholders, such as your client or teacher, on a regular basis throughout the project.
