Overview of Assessment

Assessment tasks will consist of a portfolio of in-class exercises, a project with associated documentation, and a combined theory and practical test.

You will be provided with feedback throughout the course to check your progress.

You are advised that you are likely to be asked to personally demonstrate your assessment work to your teacher to ensure that the relevant competency standards are being met.



Assessment Tasks

Assessment 1 (Worksheets): 10%
The purpose of these worksheets (Teacher handouts in-class exercises) is to provide feedback to students from class exercises. Printouts submitted during class. In addition, Element 3, Element 4, Element 5 and Element 6 of the competency will be assessed through the class exercise worksheets.

Assessment 2 (Test): 35%

The purpose of the test is to ensure that the students have understood the basic concepts of design including Determinant – Dependencies, Data Redundancy, Normalisation, BR and ERD.

Assessment 3 (Project) 30%

The purpose of this Project is to ensure that students are able to implement all the skills they have developed to date.
Firstly, students will be required to model a database using client specifications. Each student is expected to develop an individual design using VISIO. Design faults will be eliminated via several prototyping stages, using client feedback.
Sample data will then be loaded once the database design is implemented on a RDBMS platform, and queries will be created in SQL. Forms, reports and VBA modules will also be required. Basic security features and backup procedures will also be implemented.

Assessment 4 (Exam) 25%

Exam includes all the material covered all through the semester.

Other Information

Competency Requirements:

Assessment methods have been designed to measure achievement of each competency in a flexible manner over multiple tasks.

To be deemed competent students must demonstrate an understanding of all elements of a competency including employability skills.
Students are advised that they are likely to be asked to personally demonstrate their work to their teacher to ensure that the relevant competency standards are being met.

Students must achieve competency (CA) in each competency based assessment task.

Each assessment task will also carry a numerical weighting to be used for grading purposes to reflect participation, quality and professionalism.

Grading:

A student’s final grade will be the total of their accumulated marks across all assessment tasks.
