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 have two tasks for assessment - TASK 1 (Project) and TASK 2 (Security).  You must successfully complete each task to be deemed competent in this unit.

The TASK 1 (Project) requires you to design, build and validate a Database application to process transaction and store the required data for a Hospital. 

This Task consists of  three stages: Stage 1 & 3 are team submissions and Stage 2 is an individual submission. You must successfully complete each stage to be deemed competent in this task. Work for each stage of the project

(outlined below) should be submitted on the due date, as per the Teaching Schedule.


Task 1 (Project ) Stage 1 (Team):   Due: week 5

During this stage you are required to conduct research either on the net or by visiting a hospital to analyse and understand the current and future requirements (including IT infrastructure) for implementing a database to record all data necessary for a smooth functioning of a hospital.

  • Analyse business and other data to identify area of business operations (as an example payments made by patients) and boundaries of the system.
  • Analyse and submit each of these documents – a form used for capturing data, invoice issued to a patient, a weekly report generated by hospital and one query used to extract data.  
  • Based on the above analysis, develop business rules and identify possible entities.
  • Analyse IT infrastructure and identify possible IT gaps based on the strategic plan of the hospital. Also document the effect of IT developments.

Task 1 (Project) Stage 2 (Individual):  Due: week 10

 In continuation of stage 1, in this stage you need to design and build a prototype database for the hospital client. You also need to determine and evaluate the result of proposed IT changes.
 

  • Identify (or refine) business rules and assumptions from stage 1.
  • Draw ERD using VISIO tool with appropriate template.
  • Build prototype (with appropriate data types, PK and FK) with sample data in MS Access.
  • Write program / s to populate tables up to 50000 records in a table.
  • Determine and evaluate the effect of IT changes.

Task 1 (Project) Stage 3 (Team): Due: week 14

Stage 3 of the project requires you to build and validate prototype and apply normalisation principles while managing changes requested by the client.
 

  • Re-examine ERD within the team and optimise it.
  • Modify and update ERD if client suggests changes to specifications.
  • Apply normalisation principles to refine the model.
  • Build prototype in MS Access with forms and reports as required by the client.
  • Build and validate the model on MS SQL Server.
  • Document the entire model, including training requirements.
  • Develop action plans to implement proposed changes in IT infrastructure.


Students will receive feedback or confirmation for each stage of submission. It is therefore vital that any design documentation and other work required for each stage be submitted in a timely manner.

In order to be deemed competent in this Task 1 (Project) 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 the complete model and training requirements. 

You will be asked to demonstrate understanding of the project submission.
Late submissions of work required for any stage of this project will be eligible for grading at CAG (Competency Achieved) level only 
 

TASK 2 (Security) : Individual and Team : (Due in Week 11)

This task involves security design and its implementation on MS SQL Server for the above hospital client.

  • Create user accounts in MS SQL Server. (Individual submission)
  • Test these accounts for READ, WRITE, DELETE AND UPDATE. (Individual submission)
  • Design organisational security plan (Team submission)
  • Compare database access and security feature design with organisational security plan (Team submission)

  • 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.


Late Submission Procedures

You are required to submit assessment items and/or ensure performance based assessment is completed by the due dates.
If you are prevented from submitting an assessment item on time, by circumstances outside your control, you may apply in advance to your teacher for an extension to the due date of up to seven calendar days.
More Information: http://www.rmit.edu.au/students/assessment/extension
Form to use: http://mams.rmit.edu.au/seca86tti4g4z.pdf
Where an extension of greater than seven days is needed, you must apply for special consideration. Applications for special consideration must be submitted no later than two working days after the assessment task deadline or scheduled examination.

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.
