The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the performance criteria, is detailed below. Essential operating conditions that may be present with training and assessment (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) may also be included.
Database may include: | Access Informix Microsoft Structured Query Language (MS SQL) MySQL Oracle Postgre Sybase. |
SQL statements may include: | aggregate functions conditions and Boolean operators conditional operators mathematical operators table joins. |
Manipulating data may include: | creating tables and rows deleting tables and rows adding and altering data retrieving data. |
Copy and paste from the following performance criteria to create an observation checklist for each task. When you have finished writing your assessment tool every one of these must have been addressed, preferably several times in a variety of contexts. To ensure this occurs download the assessment matrix for the unit; enter each assessment task as a column header and place check marks against each performance criteria that task addresses.
