Overview of this moduleOverview of this module

• Choosing Appropriate Summative Tests• The reliability of summative (standardised) tests.

• Choosing appropriate summative tests.

• When should you administer summative tests?

1. Do you believe that your students’ NAPLAN and/or On-Demand and/or PAT results accurately reflect their level of performance?

Three QuestionsThree Questions

1. Do you believe that your students’ NAPLAN and/or On-Demand and/or PAT results accurately reflect their level of performance?

2. If we acknowledge that the odd student will have a lucky guessing day or a horror day, what about the majority?

– Do your weakest students usually receive low scores?

– Do your average students usually received scores at about expected level?

– Do your best students usually receive high scores?

Three QuestionsThree Questions

1. Do you believe that your students’ NAPLAN and/or On-Demand and/or PAT results accurately reflect their level of performance?

2. If we acknowledge that the odd student will have a lucky guessing day or a horror day, what about the majority?

– Do your weakest students usually receive low scores?

– Do your average students usually received scores at about expected level?

– Do your best students usually receive high scores?

3. However, think about your students who received high and low scores:

– Are your low scores too low? - (i.e. indicatively correct but too low)

– Are your high scores too high? - (i.e. indicatively correct but too high)

Is this reading score reliable? This high is probably too high.

Is this reading score reliable? This low is probably too low.

Summary Statements about ScoresSummary Statements about Scores

• Low scores (i.e. more than a year below expected) indicate poor performance but the actual values should be considered as indicative only

(i.e. such scores are associated with high levels of measurement error).

• High scores (i.e. more than a year above expected) indicate good performance but the actual values should be considered as indicative only.

(i.e. such scores are associated with high levels of measurement error).

• Average scores indicate roughly expected levels of performance and the actual values are more reliable

(i.e. such scores are associated with lower levels of measurement error).

Summative (Standardised) TestingSummative (Standardised) Testing• Summative testing is essential to monitor the

effectiveness of your teaching, but: – NAPLAN is not reliable for all students. Furthermore, if used

incorrectly, the other summative tests you administer (e.g. On-Demand, PAT, etc.) may also be unreliable.

– More importantly, if NAPLAN is the only summative data used in your school you are not gathering enough information to monitor the effectiveness of your teaching at all year levels. What about Prep, Yr1, Yr2, Yr4, Yr6, Yr8 and Yr10? For example:

• Year 3 NAPLAN reflects the effectiveness of your Prep-Yr2 teaching but what about the Prep teaching vs. Yr1 teaching vs. the Yr2 teaching?

• Year 9 NAPLAN reflects the effectiveness of your Yr7-Yr8 teaching but what about the Yr 7 teaching vs. Yr 8 teaching?

Things to look for in a summative testThings to look for in a summative test

• Needs to have a single developmental scale that shows increasing levels of achievement over all the year levels at your school.

• Needs to have “norms” or expected levels for each year level (e.g. The National “norm” for Yr 3 students on TORCH is an average of 34.7).

• Needs to be able to demonstrate growth from one year to the next (e.g. during Yr 4, the average student grows from a score of 34.7 in Yr 3 to an expected score of 41.4 in Yr 4 – that is 6.7 score points).

• As a bonus, the test could also provides diagnostic information.

Summative Testing and TriangulationSummative Testing and Triangulation• Even if you give the right test to the right student, sometimes, the

test score does not reflect the true ability of the student – every measurement is associated with some error.

• To overcome this we should aim to get at least three independent measures – what researchers call TRIANGULATION.

• This may include:– Teacher judgment– NAPLAN results– Other pen & paper summative tests (e.g. TORCH, PAT-R, PAT-

Maths, I Can Do Maths)– On-line summative tests (e.g. On-Demand ‘Adaptive’ testing,

PAT-Maths Plus, English Online)

Summative Testing and TriangulationSummative Testing and Triangulation

• BUT remember, more summative testing does not lead to improved learning outcomes so keep the summative testing to a minimum

When should you administerWhen should you administer

summative tests?summative tests?

Timing for Summative TestingTiming for Summative Testing

• Should be done at a time when teachers are trying to triangulate on each student’s level of performance. (i.e. mid-year and end-of-year reporting time.)

• Should be done at a time that enables teachers to monitor growth – say, every six months. (i.e. From the beginning of the year to the middle of the year and from the middle of the year to the end of the year.)

Suggested timingSuggested timing• For Year 1 – Year 6 and Year 8 – Year 10

– Late May/Early June (for mid-year reporting and six-monthly growth*)– Late October/Early November (for end-of-year reporting and six-

monthly growth)

• For Prep and Year 7 and new students at other levels– Beginning of the year (for base-line data) – but record as November the year before

– Late May/Early June (for mid-year reporting and six-monthly growth)– Late October/Early November (for end-of-year reporting and six-

monthly growth)

* November results from the year before form the base-line data for the current year. (i.e. February testing is not required for Year 1 – Year 6 or for Year 8 – Year 10)
