A nationwide online training program significantly improved Portuguese school staff’s food allergy knowledge from 62% to 80% correct answers, and staff reported feeling much more confident managing allergies. According to Gram Research analysis, this web-based training approach could help schools everywhere better prepare their staff to keep children with food allergies safe during the school day.
A new study tested whether an online training program could help school staff better understand and manage food allergies. Researchers in Portugal trained 205 school professionals using a web-based program based on expert guidelines. The results were impressive: staff knowledge about food allergies jumped from 62% correct answers before training to nearly 80% after completing the program. Staff also felt much more confident handling food allergy emergencies. According to Gram Research analysis, this type of training could help keep children with food allergies safer at school by making sure the adults around them know what to do in an emergency.
Key Statistics
A 2026 quasi-experimental study of 205 Portuguese school professionals found that a web-based food allergy training program increased staff knowledge scores from 62.1% to 79.6%, representing an 18-percentage-point improvement in understanding food allergy management.
Research on 205 school staff members showed that online food allergy training not only improved knowledge but also significantly increased staff’s perceived competence in managing food allergies and responding to emergencies at school.
A nationwide Portuguese study demonstrated that web-based food allergy training for school professionals was effective across different staff roles, including teachers, administrators, and cafeteria workers, suggesting the program’s broad applicability.
The Quick Take
- What they studied: Whether an online training program could improve how well school staff understand food allergies and feel confident managing them
- Who participated: 639 Portuguese school professionals signed up, with 205 completing the full study. This included teachers, administrators, cafeteria workers, and other school staff who interact with students daily
- Key finding: School staff who completed the online training improved their food allergy knowledge from 62% correct to 80% correct, and they reported feeling significantly more confident handling food allergy situations
- What it means for you: If your child has a food allergy and attends school, this research suggests that trained staff are better equipped to keep them safe. However, you should still communicate directly with your school about your child’s specific allergy needs and emergency plans
The Research Details
Researchers created an online training program for school staff based on guidelines from European allergy experts and Portuguese health authorities. The program covered how to recognize food allergies, prevent accidental exposures, and respond to emergencies. They tested this program with 205 school professionals in Portugal who took a knowledge quiz before training, completed the online program, and then took the same quiz afterward. Some participants only took the before-quiz, some only took the after-quiz, and some did both, which helped researchers understand the true impact of the training.
The knowledge quiz had 26 questions covering basic facts about food allergies, how to help students avoid allergens, and what school staff should do in emergencies. Researchers also asked staff to rate how confident they felt handling food allergy situations using a simple scale. They used statistical methods to compare scores before and after training and to account for differences between groups.
Schools are places where food allergies can be dangerous because students eat together, share food, and staff may not know about every child’s allergies. Previous research shows that school staff often don’t feel prepared to handle food allergy emergencies. This study tests whether online training, which is easier to deliver to many people at once, can actually improve how prepared staff feel and how much they know. If it works, schools everywhere could use this same program to train their staff
This study has several strengths: it tested a large group of real school staff across an entire country, it used a validated quiz to measure knowledge (meaning the quiz was proven to accurately test what people know), and it measured both knowledge and confidence. However, the study relied on staff self-reporting how confident they felt, which can be biased. The study also didn’t follow up months later to see if staff remembered what they learned or if it actually changed how they handle real emergencies. Additionally, this was conducted in Portugal, so results may differ in other countries with different school systems or healthcare approaches
What the Results Show
The main finding was clear and strong: school staff’s knowledge about food allergies improved significantly after the online training. Before training, staff answered about 62% of the knowledge questions correctly. After training, they answered about 80% correctly. This 18-percentage-point improvement shows the training worked well.
Staff also reported feeling much more confident in their ability to manage food allergies at school. They rated their confidence higher on a scale after completing the training. This matters because confident staff are more likely to take the right actions during an emergency.
The improvement happened across different types of school staff, suggesting the training works for teachers, administrators, cafeteria workers, and others. The online format meant staff could complete training on their own schedule, which is practical for busy schools.
The study found that the training improved knowledge across all three main topic areas tested: general understanding of food allergies, strategies to prevent accidental exposures, and proper school practices for managing allergies. This shows the program was comprehensive and effective at teaching multiple important skills. Staff also reported that the training made them feel more prepared to handle emergencies, which could translate to faster, better responses if a child has a severe allergic reaction at school
Previous research has shown that many school staff feel unprepared to handle food allergies and don’t have enough knowledge about them. This study builds on that research by showing that online training can close that knowledge gap. Other studies have tested in-person training programs, but this research shows that web-based training, which is cheaper and easier to deliver widely, can work just as well. The improvement from 62% to 80% knowledge is similar to or better than what other educational programs have achieved
The study didn’t track whether staff remembered what they learned weeks or months after training, so we don’t know if the knowledge stuck around. It also didn’t measure whether the training actually changed how staff behave during real food allergy emergencies, only whether they felt more confident. The study was conducted in Portugal with Portuguese school staff, so results might be different in other countries with different school systems or languages. Additionally, staff who volunteered to take the training might have been more motivated to learn than average staff, so results might not apply to all school workers. The study also relied on staff rating their own confidence, which can be inflated compared to actual ability
The Bottom Line
Schools should consider implementing this web-based food allergy training program for all staff members. The evidence is strong that it improves knowledge and confidence. Staff should complete the training before the school year starts and consider refresher training annually. Parents of children with food allergies should ask their school whether staff have received food allergy training and what their emergency protocols are. Confidence level: High for improving knowledge and perceived confidence; Moderate for actual emergency response since the study didn’t measure real-world behavior
This research matters most to parents of children with food allergies, school administrators, teachers, cafeteria workers, and school nurses. It also matters to public health officials who make decisions about school safety policies. Anyone involved in school food service or student supervision should care about this. The findings are less relevant to people without school-aged children or those in countries with very different school systems
Staff can improve their knowledge immediately after completing the online training, with most learning happening during the program itself. Confidence improvements also appear quickly. However, maintaining this knowledge requires reinforcement, so annual refresher training is recommended to keep skills sharp
Frequently Asked Questions
Does training help school staff handle food allergies better?
Yes. A 2026 study of 205 school staff found that online training improved food allergy knowledge from 62% to 80% correct answers and significantly increased staff confidence in managing allergies and emergencies at school.
What should I ask my child’s school about food allergy preparedness?
Ask whether staff completed food allergy training, review your child’s emergency action plan with them, confirm they know where medication is stored, and ask about their specific protocols for preventing accidental exposures during meals and school events.
Can online training work as well as in-person training for food allergies?
Research suggests web-based training can be effective. The Portuguese study showed online training improved knowledge and confidence significantly. Online training is also easier to deliver to many staff members at once, making it practical for schools.
How often should school staff get food allergy training?
The study didn’t specify, but annual refresher training is recommended to maintain knowledge and keep skills sharp. New staff should complete training before working with students, and training should be updated when school policies or guidelines change.
Will food allergy training prevent all accidents at school?
Training significantly improves preparedness and knowledge, but it’s not a complete guarantee. Parents should still communicate directly with schools about their child’s specific allergies, maintain updated emergency action plans, and ensure staff know where medication is stored.
