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

There will be 4 assessments throughout the semester. Assessments description and maximum % grade allocation as follows:

  • Assessment 1 (Worksheets): 30%
    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 2, Element 3, Element 4, Element 5 and Element 6 of the competency will be assessed through the class exercise worksheets.
  • Assessment 2 (Project) 45%
    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 3 (Test) 25%
    A final Test will be offered to students who have achieved CA.

Other Information

Competency Requirements

  • To be deemed competent students must demonstrate an understanding of all elements of this competency. Assessment methods have been designed to measure achievement of each competency in a flexible manner over multiple tasks.
  • 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.
  • All competency-based assessments for this course must be completed in order to achieve a CA (Competency Achieved) award. Each assessment task will also carry a numerical weighting to be used for grading purposes. The grade applied will only be awarded if a CA has been achieved in all compulsory assessment tasks.
  • If a student has been assessed as NYC (Not Yet Competent) in any of the assessment tasks, the weighting will carry no value until the student has obtained a CA. If a CA is achieved on re-assessment, a maximum mark of 50% of the original weighting will be granted for that assessment.
  • Re-assessments will only be granted to students who were either unsuccessful in the first attempt, or have an approved application for special consideration.
  • A final examination worth 25% will be offered to students who have achieved CA.
