According to the 2015 test program for the international student assessment for reading comprehension, for algeria, the 10th percentile with the highest reading comprehension scores 443, 42 points less than the Italian average of 485. Considering that the difference between the 50th percentile and the 90th percentile is 93 points, it can be said that out of a hundred Algerians, the fifteen-year-old most competent in reading reaches 465, 20 points less than the average Italian. In theory, if the distribution of the reading skill exactly follows the sampled distribution, only one Algerian in nine hundred understands a written text as much as the average Italian. This ignores, however, that many Algerians did not study until the age of fifteen, so this extremely overestimates the overlap with Italians as it overestimates the relative proportion of the most gifted and facilitated percentile. Only about 26-27% of Algerians went to school up to the age of fifteen, so in the remaining 74-73% the proportion will be even lower.
In short, ultimately serious statistics show us that only one Algerian out of several thousand is gifted scholastically and mentally as an average Italian. The proportion of Tunisians and Moroccans is almost equal, very similar.
For example: only one Moroccan 15-year-old student in 700 has the same level of reading comprehension as an average American, same sources. Considering that only a clear minority of Moroccans studied until the age of fifteen, this extremely overestimates the real percentage and it seems practically certain, unfortunately, that ethnic Moroccans with the same IQ as an average American are almost nonexistent, of the order of one in several thousand.
