End of unit summative assessment options for the students

As a summative assessment option, I am providing the students with two options in regards to the summative assessment for this unit. One option is that they complete an assessment that I give to them. In this assessment, they will self-assess themselves in 6 key areas based upon student learning outcomes for this unit. They will also do a general reflection that will get them focusing on how well they think they had done throughout the unit.
I discussed both options with my students and asked their thoughts. Most said that they felt it would be more accurate if I am the one that assesses them. It gave me a chance to let them know that I totally trust them in the design it themselves report and that it would be a good way to compare my assessment of them with their assessment of themselves. In some cases, it might be meeting halfway and in other cases, perhaps both teacher and student self-assessment are spot on. In my first grade 5 class, I had only 2 students choose the design yourself report which is A-OK with me. I am looking forward to seeing what they come up with. I will be presenting the same idea to my other two grade 5 classes later this week.
