As of my last knowledge update in January 2022, I don't have specific information about current discounts or offers for students at the Rijksmuseum tours in Amsterdam. However, I can provide you with some general tips on how to find student discounts for museums and cultural attractions:

1. Official Website: Check the official website of the Rijksmuseum tickets for any information on student discounts, special offers, or promotions. Museums often update their websites with the latest information on ticket prices and discounts.

2. Student ID: Many museums offer discounted rates for students, but you typically need to show a valid student ID card at the ticket counter. Make sure to bring your student ID with you when planning to visit the Rijksmuseum.

3. Third-Party Websites: Check online ticket platforms or travel websites that might offer discounted tickets for the Rijksmuseum. Sometimes, these platforms run special promotions or bundle deals that can save you money.

4. Social Media and Newsletters: Follow the Rijksmuseum on social media platforms like Facebook, Twitter, or Instagram. Museums often announce special discounts or events through these channels. Subscribing to their newsletters may also provide you with exclusive offers.

5. Student Organizations: Some universities or student organizations may have partnerships with local attractions, including museums. Check with your university's student affairs office or relevant organizations to see if they offer any discounted rates or group deals for students.

6. City Passes: Amsterdam may have city passes that include admission to multiple attractions, including the Rijksmuseum. These passes might offer better value for money compared to individual tickets.

7. Off-Peak Times: Some museums offer discounted rates during off-peak hours or days. Check if the Rijksmuseum has any such promotions, as visiting during less busy times might also save you money.

Remember to verify all information with the official sources or directly contact the Rijksmuseum for the most accurate and up-to-date details. Additionally, policies and offers may change, so it's a good idea to check for the latest information before planning your visit.
