Lustrum Celebration

27, 28 en 29 October 2022

In 2021, Maartenscollege Haren celebrated its 75th anniversary, while International School Groningen celebrated its 38th anniversary in August. The school combination does not want this fact to go unnoticed. Therefore, the lustrum will be celebrated grandly, including a student day, a symposium and a reunion in De Oosterpoort, ending with a banging party. Throughout the lustrum, money will also be raised for Kinderfonds Mamas (South Africa). 

Anyone who has attended or worked at (Sint) Maartenscollege, International School Groningen, MMS St. Walburg, Sint Martinus mavo or PC mavo de Schalm since its foundation in 1946 is warmly welcome.

Job training in Cape Town

In 2018, we, 4 teachers and 20 lln, visited Cape Town’s oldest township Nyanga, Etafeni. Nyanga is characterised by high unemployment and many people are infected with HIV. What we got to see was very impressive. Disadvantaged young people in their 20s, some already with children, were trained in, among other things, how to conduct job interviews. Training skills to boost self-confidence. Most were infected with HIV, including the youngest group we visited. Children here receive daily care, food, medicine and education.

From the students’ travel blog:
“Every participant in the programme had big goals in their lives, which was incredibly beautiful to hear and when you think about your own potential, this does make you very quiet”.

Valoyi, fit for life, fit for work.

We were so impressed by Etafeni’s drive and resilience that we visited another project aimed at young people in 2019. We were welcomed with open arms by Mama “Baby” Nxalati.
Empowering girls and young women is their goal. Getting rid of social disadvantages. Despite these tough issues, it was a joy to be there.

From the students’ travel blog:
“We got several performances and each dance was more beautiful than the last. To top it off, they put the music on permanent beep in your ear after it. We all danced together. Everyone had a big smile on their face…”
“The day not only produced a lot of sweat, but also a lot of food for thought.”

The above projects were partly funded by Children’s Fund Mamas.
Children’s Fund MAMAS supports the MAMAS of South Africa. Powerful, local women who can no longer watch children in their country suffer extreme poverty. Children who often have no food at all. No bed to sleep in. No medical care when they are sick. No access to school. No future prospects.

Whenever it is really possible again, we want to visit a project supported by the Mamas again in South Africa and at least support their projects financially. Having seen with our own eyes what a great job is done by the Mamas.
