Delaware Science DSTP Grade 8 and 11

Spring 2002


October, 2002

DSTP Facts• 3rd time administered (2000, 2001, 2002)• Measures student progress towards the Delaware

Science Content Standards• Requires students to demonstrate

– Declarative knowledge (what)– Procedural (how)– Schematic knowledge (why)

• Targets the “BIG IDEAS” in science– Structure/function relationships– Energy-matter transformations– Physical/chemical properties– Laws/theories (e.g. conservation of matter, plate tectonics)


October, 2002

Points• 32 multiple choice items of one point each • 18 short response items of 2 points each• Total of 68 points• Has four sub categories

– Inquiry (11 points or 15% of test)– Physical (19 points or 30% of test)– Earth (16 points or 25% of test)– Life (22 points or 30% of test)

• All 68 points translated into Standards-based scores ranging from 100-500. We call this the MEAN or SCALE score.


October, 2002

Performance LevelsAll scale scores are then translated into

performance levels.Level/Category

• 1 Well below Standard: Needs significant improvement

• 2 Below Standard: Needs improvement• 3 Meets Standard: Good performance• 4 Exceeds the Standard: Very good

performance• 5 Distinguished: Excellent performance
