Evidence Required

List the assessment methods to be used and the context and resources required for assessment. Copy and paste the relevant sections from the evidence guide below and then re-write these in plain English.

The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, range statement and the Assessment Guidelines for the Training Package.

Overview of assessment

Critical aspects for assessment and evidence required to demonstrate competency in this unit

Evidence of the ability to use SQL to:

create databases and tables

query one or more tables to provide required data

add, modify and delete records from tables

drop databases and tables.

Context of and specific resources for assessment

Assessment must ensure access to:

development environment

server access

database server

appropriate learning and assessment support when required.

Where applicable, physical resources should include equipment modified for people with special needs.

Method of assessment

A range of assessment methods should be used to assess practical skills and knowledge. The following examples are appropriate for this unit:

verbal or written questioning to assess candidate’s knowledge of SQL statements and procedures

review of project-based SQL application prepared by candidate.

Guidance information for assessment

Holistic assessment with other units relevant to the industry sector, workplace and job role is recommended, where appropriate.

Assessment processes and techniques must be culturally appropriate, and suitable to the communication skill level, language, literacy and numeracy capacity of the candidate and the work being performed.

Indigenous people and other people from a non-English speaking background may need additional support.

In cases where practical assessment is used it should be combined with targeted questioning to assess required knowledge.

Submission Requirements

List each assessment task's title, type (eg project, observation/demonstration, essay, assignment, checklist) and due date here

Assessment task 1: [title]      Due date:

(add new lines for each of the assessment tasks)

Assessment Tasks

Copy and paste from the following data to produce each assessment task. Write these in plain English and spell out how, when and where the task is to be carried out, under what conditions, and what resources are needed. Include guidelines about how well the candidate has to perform a task for it to be judged satisfactory.

Required skills

analytical skills to determine the elements of the SQL statement

communication skills to:

document the code

understand the client requirements

learning skills to research encountered problems independently

literacy skills to create an SQL statement using syntax

planning and organisational skills to write an SQL statement that is cross-browser compatible

problem-solving skills to translate the required outcomes from the database into SQL statements

technical skills to:

apply programming concepts

integrate SQL statements into a variety of server-side languages.

Required knowledge

features and application of:

aggregate functions:

MIN

MAX

SUM

AVG

COUNT

COUNT(*)

clause:

GROUP BY

HAVING

ORDER BY

dates and times

SQL data types

numbers

text

SQL syntax:

SELECT

FROM

WHERE

LIKE

DISTINCT

CREATE

ALTER TABLE

INSERT INTO

UPDATE

DELETE

DROP

combining condition and Boolean operators:

IN and BETWEEN conditional operators

mathematical operators

table joins.

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.
