Tips for gathering evidence to demonstrate your skills

The important thing to remember when gathering evidence is that the more evidence the better - that is, the more evidence you gather to demonstrate your skills, the more confident an assessor can be that you have learned the skills not just at one point in time, but are continuing to apply and develop those skills (as opposed to just learning for the test!). Furthermore, one piece of evidence that you collect will not usualy demonstrate all the required criteria for a unit of competency, whereas multiple overlapping pieces of evidence will usually do the trick!

Instructions to Assessors

Evidence Guide

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:

build and test regular expressions

match, replace or split text within a document or input field.

Context of and specific resources for assessment

Assessment must ensure access to:

internet in order to use online tools available for regular expressions

IDE

specific tools and licences, depending on particular platform

appropriate learning and assessment support when required

modified equipment 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 knowledge of writing regular expressions to solve common text-processing problems

evaluation of ability to:

create code to search files and input fields

handle data validation

manipulate text based on patterns.

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.

Required Skills and Knowledge

Required skills

analytical skills to:

evaluate and compare a range of tools and languages

write complex regular expressions for text processing

literacy skills to read basic technical data

problem-solving skills to:

find best solutions using regular expressions to a wide range of problems

perform basic debugging and testing skills

research skills to locate and interrogate complex and varied sources of information

technical skills to:

debug applications using basic debugging techniques

test applications using basic testing techniques

write code using an integrated development environment (IDE).

Required knowledge

maths at a basic level

basic knowledge of:

coding

database systems

object-oriented programming

open-source development tools

small-size application development.

Range Statement

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.

Languages may include:

.NET languages

C++

Java

JavaScript

MySQL

Perl

PHP

PowerShell

Python

Ruby on Rails

XML Schema

XQuery and XPath.

Regular expression engine types may include:

deterministic finite automaton (DFA)

non-deterministic finite automaton (NFA)

portable operating system interface for Unix NFA (POSIX NFA).

Patterns may include:

alternatives

character classes

grouping

repeating sequences

sub-patterns.

Test tools may include:

Grep

java.util.regex

PowerGREP

RegexBuddy

RegexMagic

RegexPal

Regular Expression Checker

Rubular.
