PYP DRA reading results 2019/20
The Developmental Reading Assessment (DRA) is an individually administered assessment of a child’s reading capabilities. It is a tool used by teachers to identify a student’s reading level, accuracy, fluency, and comprehension. Once levels are identified, teachers use this information for instructional planning purposes. This is not a test compared to other students around the world, it is an assessment that helps us track individualised growth within the same student over time which allows us to determine the effectiveness of our instructional strategies.

PYP ISA writing results 2019/20
The International School’s Assessment (created by ACER, Australia) is a writing assessment evaluating our students’ narrative and expository writing abilities. We use ISA in the primary school to determine our students’ growth and abilities in writing. ISA is compared to like-international schools (schools with similar demographics), regional schools (Asia) and all schools (the world).
Narrative/Reflective task
For this task students write a story or a reflective piece in response to a prompt, which is usually a picture. Students’ writing is assessed according to three criteria:
- Content – ideas generated and quality of thinking and reflection
- Language – sentence and paragraph structure, vocabulary and punctuation, and writer’s voice
- Spelling – accuracy and range of vocabulary.

Exposition/Argument task
For this task students write a piece setting out ideas about a proposition.
A few sentences or a short dialogue are usually provided as a prompt. Students may take an explanatory approach (exposition) or a persuasive approach (argument). Students’ writing is assessed according to three criteria:
- Content – the ideas generated and the quality of thinking demonstrated about the issue
- ESOL language – grammatical correctness and command of English syntax, sentence fluency and variation, and vocabulary (applied to all students’ writing regardless of language background)
- Structure and organisation – the overall structure of the writing and its internal coherence.
Measures of Academic Progress
Measures of Academic Progress (MAP) is an external standardised test that provides us with a data point to learn how
our students are doing in Maths and Reading in comparison to students in our like-international schools counterparts
(NESA schools), all schools in the USA, and all schools in the world.

The primary school (PYP) exhibition
All our students in Grade 5 engage in one unit of inquiry entitled “The Exhibition” as part of their six units of inquiry throughout the year. The PYP exhibition provides the culminating experience of the learner’s engagement with the PYP. It unites the teachers, learners, and parents of the class in an activity that captures the essence of the PYP transdisciplinary inquiry conducted in a spirit of personal and shared responsibility. The Exhibition represents a significant event in the life of a school, encapsulating the essence of the PYP and encouraging younger students to look forward to their final year in the programme.
Our students and teachers created a Virtual Museum for students to organise and showcase their work. The exhibition falls under the Sharing the Planet Unit, with the central idea, “Explorations of issues and opportunities inspires learning and action.” Our students inquired into pollution, sustainability, animal welfare, well-being, COVID-19, and equality.
Students held weekly Zoom meetings with their mentors, making connections to subject areas like maths, writing, and the arts. Students wrote blog posts, created song lyrics, and crunched numbers in graphs to present their research findings.
Students also took action by asking people to pay it forward with their reusable bag campaign. Students asked people to pledge to give reusable bags to others in the checkout line and to repeat the process. They created visual graphics, and songs to spread their message and promote their action. They also met with administrators to gather and share data on costs and benefits of OSC adding solar panels to the new sports complex.
Our PYP Virtual Exhibition Museum has been posted as an example by the IB and was showcased through many different online international platforms gaining much attention. Now, our teachers are mentoring others around the world through the same process.
