Success Stories

I love it just the way it is!!

Happy customers and positive reviews

I actually can’t think of a single suggestion to improve Castle Learning!!!! I absolutely love how it gives hints if the child is wrong then explains right & wrong answers. It works beautifully for grammar & punctuation skills & check-ins. It grades itself & even tells you if the child got it right on the 2nd try (I make those 1/2 credit once I start counting the grades). I love it just the way it is!!

Fast, Flexible Classroom Assessment

Happy customers and positive reviews

What a lifesaver Castle Learning is for a quick assessment of my students’ learning! Castle Learning offers hints when the student chooses the wrong answer and allows them to try the question again. The best part… Castle Learning quickly grades the assignment for you! An online assignment that students can do for a quick grade is a blessing to my life.

Targeted Review and Differentiation

Happy customers and positive reviews

I use Castle Learning in a variety of different ways. We use Castle Learning by topic to review and I love that you can select specific learning standards and topics to create assignments. We also develop assessments on particular topics and I love being able to select specific terms to search for questions. I also use it to differentiate my review for students; for example if I have a student with reading comprehension difficulty then I can go through and select reading passages for that student to practice with. I also love that there are multiple review assignments for each topic so that if a student doesn’t do well on a particular topic standard, I can easily give a retest.

Instant Grading With Actionable Data

Happy customers and positive reviews

The ‘quiz mode’ is excellent for assessing students. The scheduling feature as well as the instant grading are fantastic. It gives you concrete data on student performance.

A Must-Have Classroom Tool

Happy customers and positive reviews

There are very few things that have been as consistent about my teaching as Castle Learning. Castle Learning has continued to provide me and my students the ability to access a seemingly endless supply of questions aligned with our standards and the state exam, and the resources to use the results in meaningful ways to help my students get what they need and to fill in gaps in my instruction. The data collection that once took teachers hours and hours of manual work, Castle Learning can do in mere seconds. When we do our annual assessment of technology-based resources, Castle Learning is automatically placed in the must-have category, it does not even require a discussion.

Exceptional Support and Seamless Integration

Happy customers and positive reviews

I have used Castle Learning for years, however, this school year two things stand out. First is the excellent customer service and secondly, the new link to Google Classroom. Now, that’s a game-changer.
