About World Class Tests
â€‹
World Class Tests were conceived by the Department for Education in London, UK. They cover Mathematics and Problem Solving and are designed to provide a challenging and fun assessment for the most able 814 yearold students.
â€‹
World Class Tests help to identify and challenge able students, requiring them to apply their awareness to solve unfamiliar problems. Students are expected to communicate and explain their solutions.
â€‹
Students taking World Class Tests should be able to:
â€‹

think creatively and logically

use their thinking skills to solve problems and answer questions that are unfamiliar

communicate clearly how they think through and solve questions.
â€‹
Teachers should encourage students who may not perform well in traditional tests, but who are creative thinkers and good problem solvers, to take the World Class Tests.
â€‹
Each test has a paper component and a computer component. Students must take both. 811 yearold students have 60 minutes for each component. 1214 yearolds have 75 minutes.
Once again, a super, challenging and stimulating set of tests which the students thoroughly enjoyed  they were constantly knocking on my classroom door asking when the next test would be!

Standards
World Class Tests aim to assess a depth of understanding and application beyond the usual expectation for the age group. The assessments are internationally calibrated and are designed to provide three grades: Pass, Merit and Distinction. This international calibration is used to create the following profiles.
The number of marks required for each level is generally in line with the following requirements. The exact number of marks required varies from one test to another, as no two tests carry questions of identical difficulty.

For the 811 mathematics tests, scores in excess of 75% relate to Distinction levels of performance; scores of 5874% relate to Merit levels of performance; and scores below 58% indicate students who may be working at the Pass level of performance.

For the 811 problem solving tests, scores in excess of 60% relate to Distinction levels of performance; scores of 4559% relate to Merit levels of performance; and scores below 45% indicate students who may be working at the Pass level of performance.

For the 1214 mathematics tests, scores in excess of 72% relate to Distinction levels of performance; scores of 5471% relate to Merit levels of performance; and scores below 54% indicate students who may be working at the Pass level of performance.

For the 1214 Problem Solving tests, scores in excess of 63% relate to Distinction levels of performance; scores of 4862% relate to Merit levels of performance; and scores below 48% indicate students who may be working at the Pass level or performance.
â€‹
A Pass grade in World Class Tests suggests a student is performing at a level consistent with the top 20% of the relevant age group and is a remarkable achievement. For students whose performance does not reach the standard required for the Pass grade, certificates are issued showing that the student participated in the tests.

Identifying submerged talent
Mathematics
â€‹
Students need to apply previous mathematics knowledge to new situations and use deductive reasoning to solve unfamiliar problems. There are six major categories of functions, processes and concepts within the mathematics World Class Tests:
â€‹

Numeric

Algebraic  algebraic graphs (age 1214 group only)

Spatial

Geometric

Measures

Handling data
The image below shows an example of a computerbased mathematics question for 1214 yearolds in which students are asked to work out the sequence in the pattern of shapes then, using an algebraic or other efficient methodology, work out which shapes would correspond with the values 105 and 270.

Problem Solving
â€‹
Questions are drawn from science, design technology and mathematics, but assess highlevel problem solving skills rather than subject knowledge. Task type is the most important aspect of assessing problem solving skills within World Class Tests. These types are:
â€‹

Design or plan

Select, evaluate and recommend

Model, estimate, predict

Critique and review

Deduce from data; fit constraints

Discover or infer relationships

Translate
Below is an example of a problem solving question for 811 yearold students. The problem consists of two screens and students must work through both. On the first screen, students are expected to explore the relationship between mass of a fruit/vegetable and the amount of water displaced by the same fruit/vegetable. They also observe whether the fruit/vegetable floats or sinks.
In the example given, the carrot has a mass of 80kg and it displaces 70cm3 of water. It sinks.
Based on the observed values and relationships, students then move to page 2 of the problem, completing the table of data based on relationships they have inferred from their data.
