Summary:

- The article discusses research showing that students with last names earlier in the alphabet tend to receive higher grades compared to their peers with last names later in the alphabet.
- The study found this "last name effect" is present across multiple countries, grade levels, and subject areas, and is likely due to teachers' unconscious biases and the order in which they grade assignments.
- The findings highlight the need for education systems to implement strategies to mitigate these types of unintended biases that can disadvantage certain students.
