4. Analysis of Existing Screenings
• Today: multiple screenings to choose from
• Most screenings only available as paper-pencil screening
• Some also provide digital versions
• Analysis of existing screenings should show:
• Similarities
• Best practices

7. Design and Structure of App
• Children at preschool age do not have necessary skills in reading and
writing
• How to communicate assignment’s task to children?
• Make use of a visual language
• How to enable children to perform input?
• Make input options as intuitive as possible
• Children should stay motivated for several minutes
• Wrap screening into a, for the child interesting, frame-story
• Make use of a child-friendly graphical character

17. Automatic Evaluation
• Considers all results of current screening run
• Calculates level of development in 7 different educational subjects
• Calculations given by developmental psychologists

• 3 different levels of development:
• Slight special educational needs
• Obvious special educational needs
• A checkmark representing no educational needs
