LISG delivers a broad and balanced curriculum aligned with California Common Core State Standards, supplemented by UAE Ministry of Education requirements for Arabic as a first language, Islamic Education, and Social Studies - all taught in Arabic. English is the medium of instruction across all other subjects, with a deliberate emphasis on strengthening English as an additional language for the majority of students who enter with limited English proficiency. The school is accredited by Cognia (formerly AdvancED), which validates the school's US High School Diploma for international university acceptance. Students are prepared for the SAT, AP, and TOEFL examinations, providing a recognised pathway to higher education globally and within the UAE.
The 2025 ADEK Irtiqa inspection provides the most granular picture of academic performance. In English, attainment is Very Good in KG but declined to Good in Cycles 1, 2, and 3 - largely attributed to inconsistent vocabulary development and writing skills. Progress, however, remained Very Good across all phases, which is an important distinction: students are making strong gains from their starting points even where absolute attainment benchmarks remain a work in progress. In mathematics, attainment is Very Good in KG and Cycle 1, Good in Cycles 2 and 3, with progress regressing to Good in Cycle 2 - inspectors linked this to inconsistency in applying arithmetic and algebraic skills. Science attainment is Very Good in KG, Good in Cycles 1-3, while progress remains Very Good in most phases. Islamic Education is a relative strength, rated Very Good for attainment and progress in KG, Cycle 2, and Cycle 3. Arabic as a first language is Good in KG and Cycle 1, rising to Very Good in Cycles 2 and 3.
On international benchmarks, the picture is honest and sobering. In PISA 2022, 15-year-old students scored 421 in reading (international average: 476), 417 in mathematics (average: 472), and 431 in science (average: 485) - all below both school targets and international norms. TIMSS 2023 results show Grade 4 mathematics at 424 (international average: 503) and Grade 8 mathematics at 429 (average: 478). PIRLS 2021 placed Grade 4 readers at 459, within the Low International Benchmark. The school's leadership acknowledges these gaps and has embedded TIMSS- and PISA-style questions, MAP assessments, and structured interventions into the curriculum - a credible response, though the impact is still developing.
Academic support provision is a genuine strength. The school identifies 141 students of determination and deploys diagnostic tools and targeted interventions to support them. A full-time counsellor has been appointed, strengthening career and university guidance. Gifted and talented provision is acknowledged as still developing - ADEK inspectors noted that differentiation for higher-attaining students is inconsistent across phases. The school uses MAP (NWEA), RAZ Kids, IXL, Exact Path, and Heggerty phonics as core assessment and intervention tools. Learning skills - collaboration, critical thinking, and problem-solving - are rated Very Good across all phases, suggesting a strong classroom culture even where measurable outcomes lag international norms.
