The History and Development of Intelligence Tests
The concept of measuring intelligence dates back to the early 20th century. French psychologist Alfred Binet developed the first intelligence test in 1905 to identify children needing special education support. His work laid the foundation for modern IQ testing.
Evolution of IQ Testing
Over the years, intelligence tests have evolved to assess multiple cognitive abilities. Key milestones include:
1916 – Lewis Terman revised Binet's test into the Stanford-Binet Intelligence Scale , introducing the IQ score concept.
1939 – David Wechsler developed the Wechsler Adult Intelligence Scale (WAIS) , expanding IQ assessment to adults.
Modern Era
– Today's intelligence tests incorporate digital formats, adaptive testing, and broader cognitive measurement.

24 Moroccan Students Secure Spots at France's Elite École Polytechnique in 2025
Marrakech – Twenty-four Moroccan students have been admitted to the prestigious École Polytechnique in Paris for the upcoming academic year. These students, all from classes préparatoires aux grandes écoles (CPGE), will join the X2025 promotion in September after successfully passing the rigorous entrance examinations. According to a statement from École Polytechnique, 56 Moroccan candidates initially qualified for the written phase of the competitive exam. The 24 successful candidates will now receive exceptional training in science and engineering, coupled with the institution's characteristic human and military education. 'These figures confirm the excellent results of Moroccan students in the École Polytechnique entrance examination,' the institution stressed in its press release. The 'polytechnicien' engineering program admission process consists of two main phases. The first involves written tests covering scientific subjects such as mathematics and physics, as well as literary examinations (French not mandatory and a modern language). Successful candidates then proceed to oral examinations that evaluate both their scientific knowledge and language skills. École Polytechnique has maintained long-standing close ties with Morocco, particularly through academic and research collaborations with Mohammed VI Polytechnic University (UM6P), one of its principal partners in the country. The two institutions have signed cooperation agreements enabling various joint projects in research, entrepreneurship, and academics. From Benguerir to Paris, Lydex students dominate admissions This achievement builds on Morocco's growing academic excellence in France. The Lycée d'Excellence de Benguérir (Lydex) secured fourth position among institutions preparing students for École Polytechnique, according to French magazine L'Etudiant's December 2024 ranking. It follows Paris's Henri-IV (third), while Louis-le-Grand and Sainte-Geneviève occupy the first and second positions respectively in the Mathematics-Physics (MP) stream. Between 2020 and 2024, approximately 7% of students admitted to École Polytechnique came from Lydex, which is 'generally reserved for the most brilliant students in the country.' Lydex had previously ranked second in the Mathematics-Physics (MP) stream in February of the same year. The Moroccan institution has demonstrated consistent success in recent years. In 2023, it set a record with 20 students gaining admission to Polytechnique, representing one-third of places allocated to international students. In 2022, Lydex had 24 students qualify for the entrance exams, including six female students – making it the only Moroccan institution to place women in the oral examination phase that year. Historical data shows Lydex's consistent performance: in 2019, 11 out of 15 Lydex candidates successfully passed Polytechnique's oral examinations, followed by 17 out of 21 in 2020, and 11 out of 25 in 2021. According to Campus France's 2024 report, Moroccan students constitute the largest foreign student community in France, with 45,162 students enrolled during the 2022-2023 academic year. Morocco leads in engineering school enrollments with 6,110 students, marking a 26% increase between 2017 and 2022. Established in 2015 in Benguerir's Mohammed VI Green City, Lydex operates with a strong social inclusion mission. Approximately 90% of students receive full scholarships, with additional financial support provided to disadvantaged students for supplementary expenses. The residential campus model includes sports activities to help students manage the intensive study program's demands.

It offers exceptional learning facilities, including laboratories for all disciplines, a theater, a semi-Olympic swimming pool, and sports fields meeting international standards. The OCP Foundation signed a partnership with the Ministry of National Education and UM6P in July 2023 to promote educational excellence through innovative initiatives. This collaboration focuses on encouraging innovation, fostering a culture of excellence, empowering educational stakeholders, and creating sustainable impact. The Lydex model has inspired similar initiatives, such as the Mediterranean Lyceum (Lymed) created by the Tanger Med Foundation. Located in Tetouan, Lymed opened for the 2021-2022 academic year with its first students enrolled in the MPSI (Mathematics, Physics, Engineering Sciences) program. The campus, situated in the Tetouan Shore area near Cabo Negro, spans 3 hectares with state-of-the-art facilities. In 2023, Lymed achieved remarkable results: all 48 students from its first class were admitted to French engineering schools, including four to École Polytechnique (with one being the highest-ranked Moroccan in the competition), 16 to Mines-Ponts schools, and 10 to Centrale schools in France.

UM6P, Tanger Med Launch AI Program to Transform Industrial Operations
Marrakech – The University Mohammed VI Polytechnique (UM6P) and Tanger Med Group signed a new partnership agreement on Tuesday, launching the 'AI Tanger Med' program. This initiative mobilizes students from the 1337 MED campus to develop artificial intelligence solutions for real industrial challenges faced by companies within the Tanger Med ecosystem. The program operates under the scientific guidance of UM6P's Artificial Intelligence Laboratory to ensure strong academic foundations while addressing practical operational needs. Students work on concrete projects involving automation, data analysis, and cybersecurity – all directly connected to port, logistics, and industrial operations. 'The terrain becomes a classroom and puts innovation at the service of operational excellence,' states the joint press release from both organizations. This approach creates a dual benefit: Tanger Med brings together its partners to formulate operational problems, while students gain an immersive, structured experience connecting their technical skills to industrial realities. The agreement builds upon a successful collaboration that began in 2021 with the establishment of the 1337 MED campus in Martil near Tangier. Today, this campus hosts nearly 400 students trained through a unique model in Morocco based on project learning, mutual assistance, and autonomy. Without traditional lectures or professors, students develop problem-solving skills through collaborative projects. This partnership propels the North African country's digital landscape forward alongside other technological initiatives. Earlier in July, the Ministry of Digital Transition held the first national conference on artificial intelligence under the theme 'An Efficient and Ethical AI Strategy Serving Our Society.' During this conference, Digital Transition Minister Amal El Fallah Seghrouchni declared that 'integrating AI into the national strategic horizon is a prerequisite for sovereignty.' She asserted that AI must be viewed 'not as a subsidiary technical solution, but as a fundamental institutional responsibility.' The government has recently launched several initiatives to position Morocco as a regional leader in AI. On July 22, a protocol agreement between government ministries, the Moroccan Investment and Export Development Agency (AMDIE), and the French group, Onepoint, established a data and AI excellence center in the Casablanca-Settat region. The project plans to recruit 500 Moroccan engineers over four years, strengthening expertise in AI, middleware, and data management. Additionally, the Ministry of Digital Transition signed partnerships with UM6P in early July to advance research in data centers and digital sovereignty as part of the 'Morocco Digital 2030' national strategy.

Moroccan Student in Coma in Paris as Family Seeks Urgent Help for Second Liver Transplant
The family of Aya Boumzebra, a young Moroccan student, has launched an urgent call for financial support as she lies in a coma at a hospital in France. Currently in her fourth year at the École Supérieure d'Architecture de Marrakech, the 24-year-old needs a second liver transplant to survive. Aya's condition has worsened sharply following complications after a previous transplant. The initial surgery, carried out a year ago, had gone well. But a recent infection disrupted her recovery and led to a medical emergency that now requires immediate surgical intervention. She was first treated at the Ibn Sina University Hospital in Rabat. After her condition failed to improve, doctors transferred her to the Paul Brousse Hospital near Paris. There, she fell into a coma last week. Specialists at the Paris hospital have confirmed the need for a second liver transplant, describing it as urgent. The required procedure comes at a high cost. The family must raise €250,000, over MAD 2.6 million, a sum far beyond their current means. In response, Aya's relatives have turned to the public, asking for help to keep their daughter alive. According to converging reports, they launched a donation campaign through the French crowdfunding platform Leetchi and shared banking details for direct transfers in Morocco. The effort quickly reached social media, where friends, influencers, and strangers began spreading the appeal. Boumzebra grew up with a liver condition and endured years of treatment. After her transplant last year, she returned to her studies, determined to graduate. Her recent relapse has devastated those close to her. Aya's mother and father remain in Paris at her bedside, hoping the funds arrive in time. Her case is now officially under the care of the association Yallah Netteaawnou, led by Nawal Filali. The organization has taken charge of all donations and communications in coordination with Aya's family. A professional bank account has been created under the association's name, and all previously collected funds, including those from Aya's aunt's personal account, will be transferred to it. Thanks to the immense public support, the initial sum requested by Paul Brousse Hospital in Paris, covering reanimation and intensive care, has already been secured. However, this amount does not include the €250,000 needed for the liver transplant. All previous donation campaigns have been closed, and the association has asked supporters to rely only on its official channels for future updates. The association is now awaiting a response from Morocco's National Social Security Fund (CNSS) regarding a potential full or partial coverage of the transplant procedure. Until then, no new fundraising efforts will be launched, and all updates will come directly from Yallah Netteaawnou in coordination with the family. In its latest statement, the association warned against unauthorized fundraising campaigns and said legal action would be taken against any misuse of the case. It urged the public to remain vigilant and keep Aya in their thoughts as she remains in a coma, with her condition being closely monitored by doctors in Paris.
